Hexaaqua-cobalt(II) bis-{[N-(4-meth-oxy-2-oxidobenzyl-idene)glycylglycinato]nickel(II)} hexa-hydrate.

In the title compound, [Co(H(2)O)(6)][Ni(C(12)H(11)N(2)O(5))](2)·6H(2)O, the Ni(II) atom has a nearly square-planar coordination with two N and two O atoms of the N-(4-meth-oxy-2-oxidobenzyl-idene)glycylglycinate Schiff base ligand (L(3-)). The Co(II) atom sits on an inversion center and is coordinated to six aqua ligands in a slightly distorted octa-hedral geometry. The [Co(H(2)O)(6)](2+) cations and [NiL](-) anions form columns along the a axis by O-H⋯O hydrogen bonds. Additional hydrogen bonds between the uncoordinated and coordinated water molecules help to consolidate the crystal packing.

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.
