Chlorido(4,4′,4′′-tri-tert-butyl-2,2′:6′,2′′-terpyridine)­platinum(II) tetra­fluorido­borate

Abstract

In the title compound, [PtCl(C27H35N3)]BF4, the PtII atom is in a pseudo-square-planar coordination, which is typical of Pt–terpyridine complexes. The Pt—Cl bond distance is 2.2998 (7) Å. The Pt—N distance of the N atom on the central pyridine is 1.931 (2) Å, while the peripheral N atoms have Pt—N distances of 2.018 (2) and 2.022 (2) Å. The cations pack as dimers in a head-to-tail orientation with an inter­molecular Pt(...)Pt distance of 3.5214 (2) Å and Pt(...)N distances of 3.527 (2), 3.873 (2) and 4.532 (2) Å. In the crystal, cations and anions are linked by weak C—H(...)F hydrogen-bonding inter­actions.

Comment

In the structures of the [(tbtrpy)PtCl]+ (tbtrpy = 4,4',4''-tri- tert-butyl-2,2':6',2''-terpyridine) complexes with either chloride (Batrice et al., 2010), tetrafluoroborate (title complex) or perchlorate (Lai et al., 1999) counterions, the bond distances and angles around the platinum atom are all similar. The cations in these structures all pack as dimers in a head-to-tail orientation. Interestingly, the interplanar (Pt, Cl and N atoms) distance seems to be related to the size of the anion with the Cl-, BF4-, and ClO4- being 3.283, 3.390 and 3.536 Å, respectively. In addition to the size of the counterion, solvent is also noted as playing a role in the ability of these types of complexes to interact significantly with each other (Bailey et al., 1995). In the title complex, the cations and anions are linked by weak H-bonding interactions between C—H···F (Table 1).

The intermolecular distance is within a suitable distance for favorable π-π interactions. So the bulky tert-Butyl groups of the tbtrpy ligand do not appear to alter the ability of this complex to form suitable interactions between the two molecules of the dimer. The difference in color between the crystal (red) and the powder (yellow) is, likewise, attributed to this dimer interaction (Angle et al., 2006).

Experimental

[(tbtrpy)PtCl]Cl was synthesized according to modifications on a published procedure (Howe-Grant and Lippard, 1980). This [(tbtrpy)PtCl]+ complex was reacted with various aromatic thiol ligands (SAr). One such product containing a [(tbtrpy)Pt(SAr)]Cl (0.02 mmol) complex was reacted with sodium tetrafluoroborate (0.10 mmol) in a solution of methanol and isolated through condensation and precipitation with diethyl ether (94% yield). Crystals of the title compound were grown from the vapor diffusion of cyclohexane into a dichloromethane solution containing [(tbtrpy)Pt(SAr)]BF4 and [(tbtrpy)PtCl]BF4.

Refinement

H atoms were placed in idealized positions with C—H = 0.95 and 0.98 Å for aryl and methyl H-atoms, respectively, and allowed to ride on their parent atoms with Uiso(H) 1.2 (aryl C) or 1.5 (methyl C) × Ueq of the parent atoms. The largest residual electron density in the final difference map was located close to the platinum atom (0.83 Å) and was most likely due to imperfect absorption corrections frequently encountered in heavy-metal atom structures.

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 > σ(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.
