catena-Poly[[[diaqua­(nitrato-κ2 O,O′)(2,2′:6′,2′′-terpyridine-κ3 N,N′,N′′)ytterbium(III)]-μ-cyanido-κ2 N:C-[dicyanido­platinum(II)]-μ-cyanido-κ2 C:N] acetonitrile monosolvate]

Abstract

The title compound, {[PtYb(CN)4(NO3)(C15H11N3)(H2O)2]·CH3CN}n, was isolated from solution as a one-dimensional coordination polymer. The Yb3+ site has ninefold coordination with a distorted tricapped trigonal–prismatic geometry, while the PtII ion is coordinated by four cyanide groups in an almost regular square-planar geometry. cis-Bridging by the tetra­cyanidoplatinate(II) anions links the Yb3+ cations, forming chains. Additionally, each Yb3+ is coordinated by two water mol­ecules, one bidentate nitrate anion, and one tridentate 2,2′:6′,2′′-terpyridine mol­ecule. O—H(...)N hydrogen-bonding inter­actions are found between adjacent chains and help to consolidate the crystal packing. In addition, π–π stacking inter­actions exist between the terpyridine ligand and the two corresponding terpyridine ligands along the adjacent chain (average inter­planar distance = 3.667 Å). Moderate Pt(...)Pt inter­actions [3.5033 (4) Å] are observed in the structure.

Comment

One of our research goals is to prepare systems in which weak Ln3+ emissions are enhanced through the use of sensitizing ligands. Recent efforts in our lab have focused on lanthanide compounds that incorporate both tetracyanidoplatinate(II) anions (TCP) and 2,2':6',2''-terpyridine (tpy), to achieve this goal (Maynard et al., 2008; Maynard, Smith, Ladner et al., 2009), since both of these ligands are known sensitizers for Ln3+ (Gliemann & Yersin, 1985; Mukkala et al., 1995). We have also reported the structures of several related compounds (Maynard et al., 2010; Maynard, Smith & Sykora, 2009).

The title compound is a cocrystal similar to several previously reported compounds in that it contains one-dimensional [Yb(C15H11N3)(H2O)2(NO3)Pt(CN)4]n chains similar to those found in Eu(C15H11N3)(H2O)2(NO3)Pt(CN)4].CH3CN (Maynard et al., 2008), [Nd(C15H11N3)(H2O)2(NO3)Pt(CN)4].CH3CN.0.5C15H11N3 (Maynard, Smith & Sykora, 2009)), and Yb(C15H11N3)(H2O)2(NO3)Pt(CN)4].0.5CH3CN.1.5H2O (Maynard et al., 2010). The major structural differences can be attributed to the crystallization of solvent or guest molecules between the 1—D chains. While the formulae of the title compound and Eu(C15H11N3)(H2O)2(NO3)Pt(CN)4].CH3CN appear similar, the compounds are not true isomorphs due to different packing arrangements.

The neutral, 1—D [Yb(C15H11N3)(H2O)2(NO3)(Pt(CN)4)]n chains in the structure of the title compound are illustrated in Figure 1 and a thermal ellipsoid plot is shown in Figure 2. The chains are formed by the linkage of the Yb3+ cations by cis-bridging TCP. The coordination of Yb1 is ninefold and is best described as a distorted [YbO4N5] tri-capped trigonal prism.

The packing diagram of the title compound along the a axis is shown in Figure 3. There are two dominant inter-chain features that exist in the compound: those of Pi-stacking interactions whose inter-planar distances average 3.667 Å, and Pt···Pt interactions of 3.5033 (4) Å. These former interactions are between the coordinated tpy of one chain and the tpy of the adjacent chain, overlapping one-two rings from the inversely directed tpy ligands that resideon opposite sides of the adjacent chains, thus bringing them into partial alignment. This situation is unlike that in [Eu(C15H11N3)(H2O)2(NO3)Pt(CN)4].CH3CN, where the tpy ligands are not all unidirectional along the chain, as they are in the title compound, but instead flip nearly 180° with each successive cation. The dimeric Pt···Pt interactions occur between parallel TCP ligands on adjacent chains, opposite that of the tpy Pi-stacking interactions. Additional features for the title compound include channels along the a axis that contain acetonitrile solvate molecules (hydrogen bound to water) and additional inter-chain O—H···N h-bonding interactions between water molcules and TCP anions of neighboring chains (Table 1).

Experimental

Yb(NO3)3.6H2O (Strem, 99.9%), K2Pt(CN)4.3H2O (Alfa Aesar, 99.9%), and 2,2':6',2''-terpyridine (tpy) (Aldrich, 98%) were used as received without further purification. The reaction proceeded by reacting a 1:1:1 molar ratio of reactants: 1 ml of a 0.10 M solution of Yb(NO3)3 was mixed with 1 ml of a 0.10 M solution of Pt(CN)42– followed by layering of 1 ml of 0.10 M tpy. The tpy and Yb3+ solutions were prepared in acetonitrile, whereas the Pt(CN)42– solution was prepared using acetonitrile, with drop-wise addition of H2O until the K2Pt(CN)4.3H2O was completely dissolved. Slow evaporation of the solvents over a period of 1–2 weeks resulted in the crystallization of the title compound as colorless prisms in a yield of 46%.

Refinement

Hydrogen atoms on the terpyridine ring and acetonitrile molecule were placed in calculated positions (the acetonitrile H atoms were allowed to rotate but not to tip) and allowed to ride during subsequent refinement, with Uiso(H) = 1.2Ueq(C) and C—H distances of 0.93 Å for the former and Uiso(H) = 1.5Ueq(C) and C—H distances of 0.96 Å for the latter. H-atoms contained in the water molecules were initially located in the difference map and then constrained to have O—H distances of 0.85 Å and Uiso(H) = 1.5Ueq(O).

Special details

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > 2σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
