Abstract

The asymmetric unit of the title compound, {[Co(3)Yb(2)(C(5)H(2)N(2)O(4))(6)(H(2)O)(4)]·2H(2)O}(n), contains one Yb(III) ion, two Co(II) ions (one situated on an inversion centre), three imidazole-4,5-dicarboxyl-ate ligands, two coordinated water mol-ecules and one uncoordinated water mol-ecule. The Yb(III) ion is seven-coordinated, in a monocapped trigonal prismatic coordination geometry, by six O atoms from three imidazole-4,5-dicarboxyl-ate ligands and one water O atom. Both Co(II) ions are six-coordinated in a slightly distorted octa-hedral geometry. The Co(II) ion that is located on an inversion center is coordinated by two O atoms from two water mol-ecules, as well as two O atoms and two N atoms from two imidazole-4,5-dicarboxyl-ate ligands. The second Co(II) ion is bonded to four O atoms and two N atoms from four imidazole-4,5-dicarboxyl-ate ligands. These metal coordination units are connected by bridging imidazole-4,5-dicarboxyl-ate ligands, generating a three-dimensional network. The crystal structure is further stabilized by N-H⋯O, O-H⋯O and C-H⋯O hydrogen-bonding inter-actions involving the water mol-ecules and the imidazole-4,5-dicarboxyl-ate ligands.

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.
