The title polymeric compound, [Cu2(C8H7O2)4]n, was synthesized by the reaction of copper acetate with aqueous phenylacetic acid. The unique CuII atom is coordinated by five O atoms from the carboxylate groups of phenylacetate ligands, and the strongly distorted octahedral coordination environment is completed by a Cu—Cu bond of 2.581 (2) Å, at whose mid-point is located an inversion centre. The consists of infinite polymeric linear chains of Cu2+ ions, running along [100], linked by bridging phenylacetate groups.

To a solution of Cu(CH3CO2)2.H2O (0.049 g, 0.25 mmol) in methanol (10 cm3) at room temperature was added solid phenylacetic acid (0.068 g, 0.5 mmol) in small portions under constant stirring.The mixture was then filtered and the filtrate allowed to stand for 10 days, after which small blue block-like crystals of the title complex were obtained.
The C-bound hydrogen atoms were placed in geometrically idealized positions and constrained to ride on their parent atom positions with a C–H distances of 0.93 Å and with Uiso(H) = 1.2Ueq(C).
Carboxylate groups may interact as bridging ligands with divalent transition metals present in the biological environment, thereby altering the bioavailability of the drug. Moreover, it is well known that many complexes of divalent transition metals are capable of catalyzing the hydrolysis of RNA (Stem et al., 1990; Kimura, 1994). The coordination chemistry of polynuclear Cu2+ complexes bridged by phenylacetate has not been much reported. To date, we have found only two report of a dinuclear Co2+ complexes, namely tetrakis(phenylacetato)bis[(quinoline-N)-cobalt(II)] (Cui et al., 1999), µ-Aqua-κ2O:O-di-µ-phenylacetato-κ4O:O' -bis[(1,10-phenanthroline-κ2N,N')(phenylacetato- κO)cobalt(II)](Kong et al., 2005a) and dinuclear Cu2+ complex, namely tetrakis(phenylacetato)bis-[(N,N-dimethylformamide)copper(II)] (Kong et al., 2005b), in which all phenylacetate groups are in bidendate bridging modes. In this paper, we describe the of new polymeric complex obtained by reaction of phenylacetic acid with copper(II) acetate.
The molecular geometry of the title compound is illustrated in Fig.1. Each CuII atom is six-coordinated by five O atoms from carboxylate groups of the phenylacetate and is completed by a Cu—Cu bond in a strongly distorted octahedral coordination, in which an inversion center is located at the mid-point of the Cu—Cu bond with a Cu···Cu distance is 2.581 (2) Å. The Cu—O bond length ranges from 1.944 (7) to 2.200 (6) Å. The two carboxylate groups [O3/C1/O1 and O2/C2/O4] are almost perpendicular to one another with a dihedral angle of 78.4 (16)°. The structure, consists of polymeric infinite linear chains running along [100](Fig.2). The chains are formed by Cu2+ ions linked with bridging phenylacetate groups.

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. |

Carboxylate groups may interact as bridging ligands with divalent transition metals present in the biological environment, thereby altering the bioavailability of the drug. Moreover, it is well known that many complexes of divalent transition metals are capable of catalyzing the hydrolysis of RNA (Stem et al., 1990; Kimura, 1994). The coordination chemistry of polynuclear Cu2+ complexes bridged by phenylacetate has not been much reported. To date, we have found only two report of a dinuclear Co2+ complexes, namely tetrakis(phenylacetato)bis[(quinoline-N)-cobalt(II)] (Cui et al., 1999), µ-Aqua-κ2O:O-di-µ-phenylacetato-κ4O:O' -bis[(1,10-phenanthroline-κ2N,N')(phenylacetato- κO)cobalt(II)](Kong et al., 2005a) and dinuclear Cu2+ complex, namely tetrakis(phenylacetato)bis-[(N,N-dimethylformamide)copper(II)] (Kong et al., 2005b), in which all phenylacetate groups are in bidendate bridging modes. In this paper, we describe the crystal structure of new polymeric complex obtained by reaction of phenylacetic acid with copper(II) acetate.
The molecular geometry of the title compound is illustrated in Fig.1. Each CuII atom is six-coordinated by five O atoms from carboxylate groups of the phenylacetate and is completed by a Cu—Cu bond in a strongly distorted octahedral coordination, in which an inversion center is located at the mid-point of the Cu—Cu bond with a Cu···Cu distance is 2.581 (2) Å. The Cu—O bond length ranges from 1.944 (7) to 2.200 (6) Å. The two carboxylate groups [O3/C1/O1 and O2/C2/O4] are almost perpendicular to one another with a dihedral angle of 78.4 (16)°. The structure, consists of polymeric infinite linear chains running along [100](Fig.2). The chains are formed by Cu2+ ions linked with bridging phenylacetate groups.
