Tetra­kis(μ-phenyl­acetato-κ²O:O′)bis­[(N,N-dimethyl­formamide-κO)copper(II)]

In the crystal structure of the title complex, [Cu₂(C₈H₇O₂)₄(C₃H₇NO)₂], two independent dinuclear Cu^II complex mol­ecules, bridged by phenyl­acetate anions, are located on inversion centres. The Cu...Cu separations of 2.6414 (8) and 2.6261 (8) Å suggest no bonding between the Cu atoms. The Cu^II ions exist in a square-pyramidal coordination environment, defined by one N,N-dimethyl­formamide and four phenyl­acetate O atoms.

μ-Aqua-κ²O:O-di-μ-phenyl­acetato-κ⁴O:O′-bis­[(1,10-phenanthroline-κ²N,N′)(phenylacetato-κO)cobalt(II)]

The title mol­ecule, [Co₂(C₈H₇O₂)₄(C₁₂H₈N₂)₂(H₂O)], is a dinuclear Co^II complex which is located on a twofold symmetry axis. Each Co^II ion is six-coordinated by three O atoms of different phenyl­acetate ligands, two N atoms of the 1,10-phenanthroline ligands and one O atom of a water mol­ecule, giving a distorted octa­hedral geometry. The two Co^II atoms are bridged by two phenyl­acetate groups and the water mol­ecule lying on the twofold axis. The Co...Co distance is 3.553 (2) Å. A one-dimensional supramolecular chain is constructed by π–π stacking inter­actions between adjacent 1,10-phenanthroline mol­ecules.
