catena-Poly[[[tetra­aqua­cobalt(II)]-μ-4,4′-bipyridine-κ2 N:N′] 2-[4-(2-carboxyl­ato­eth­yl)phen­oxy]acetate]

Abstract

In the title complex, {[Co(C10H8N2)(H2O)4](C11H10O5)}n, the unique CoII ion lies on an inversion center and is coordinated by two N atoms from two 4,4′-bipyridine ligands and four O atoms from four water mol­ecules in a slightly distorted octa­hedral coordination geometry. The 4,4′-bipyridine ligands bridge CoII ions into a one-dimensional chain structure. In the crystal structure, inter­molecular O—H(...)O hydrogen bonds link cations and anions into a three-dimensional network. The dianions are completely disordered about an inversion center.

Comment

In recent years, assembly of high-dimensional supramolecular coordination polymers via coordination bonds, hydrogen bonds, and π···π stacks (Ye et al., 2005) have received much attention and carboxylic acid compounds as good donors and acceptors of hydrogen bonds have been widely utilized as ligands. 3-(4-hydroxyphenyl)propanoic acid (Tan et al., 2007) a pseudo-symmetric carboxylate acid is a potential multidentate ligand and a good donor and acceptor of hydrogen bonds, but its coordination polymers are less investigated. 4,4'-bipyridine is a neutral linear bifunctional ligand that is widely used as an excellent spacer in the construction of supramolecular architectures (Cussen et al., 2002; Tao et al., 2000). Here, we report the synthesis and crystals structure of a cobalt supramolecular complex formed using with 4,4'-bipyridine and 3-(4-(carboxymethoxy)phenyl)propanoic acid.

The asymmetric unit and some symmetry related atoms are shown in Fig. 1. The unique CoII ion lies on an invesion center and is coordinated by two nitrogen atoms from two 4,4'-bipyridine ligands and four oxygen atoms from four water molecules in a slightly distorted octahedral coordination geometry. The molecules of 3-(4-(carboxymethoxy)phenyl)propanoic acid are completely deprotonated but remain uncoordinated, and the 4,4'-bipyridine ligands act as bridging to join the CoII ions into a one-dimensional chain structure, which is further linked to a 3-D network through intermolecular O—H···O hydrogen bonds.

Experimental

A mixture of CoCl2.2H2O (0.1 mmol), 4,4'-bipyridine (0.1 mmol), 3-(4-(carboxymethoxy)phenyl)propanoic acid (0.1 mmol) and 10 ml water was placed in a tube and heated at 363 K for 6 h, then cooled to room temperature. Upon cooling to RT, a few red crystals were obtained. Anal. Calcd for C21H26N2O9Co (509.37): C, 49.47; H, 5.10; N, 5.50%; Found: C, 49.23; H, 4.98; N, 5.19%.

Refinement

The water H atoms were located in a difference Fourier map but were included in fixed positions in riding-model approximation with the O—H distances in the range 0.8245–0.8271 Å and Uiso(H) = 1.5Ueq(O); all other H atoms were placed in geometrically idealized positions with CH(methylene) = 0.97 Å, C—H(aromatic) = 0.93 Å, and Uiso(H) = 1.2Ueq(C). The dianion is completely disordered over an inversion center. The SADI and EADP commands in SHELXL (Sheldrick, 2008) were used to model the disorder.

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.
