Poly[[tetra-aqua-(μ(4)-imidazole-4,5-dicarboxyl-ato)(μ(3)-imidazole-4,5-dicarboxyl-ato)-μ(3)-sulfato-μ(2)-sulfato-cobalt(II)dierbium(III)] monohydrate].

The asymmetric unit of the title compound, {[CoEr(2)(C(5)H(2)N(2)O(4))(2)(SO(4))(2)(H(2)O)(4)]·H(2)O}(n), contains a Co(II) ion, two Er(III) ions, two imidazole-4,5-dicarboxyl-ate (imdc) ligands, two SO(4) (2-) anions, four coordinated water mol-ecules and one uncoordinated water mol-ecule. The Co(II) ion is six-coordinated by two O atoms from two coordinated water mol-ecules and two O atoms and two N atoms from two imdc ligands in a slightly distorted octa-hedral geometry. Both Er(III) ions are eight-coordinated in a bicapped trigonal-prismatic coordination geometry. One Er(III) ion is coordinated by four O atoms from two imidazole-4,5-dicarboxyl-ate ligands, three O atoms from three SO(4) (2-) anions and one water O atom; the other Er(III) ion is bonded to five O atoms from three imdc ligands, two O atoms from two SO(4) (2-) anions as well as one coordinated water mol-ecule. The coordinated metal units are connected by bridging imdc ligands and sulfate ions, generating a two-dimensional heterometallic layer. The two-dimensional layers are stacked along the b axis via N-H⋯O, O-H⋯O and C-H⋯O hydrogen-bonding inter-actions between water mol-ecules, SO(4) (2-) anions, and imdc ligands, generating a three-dimensional framework.

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.
