Bis{2-[(guanidinoimino)­meth­yl]phenolato-κ³N,N′,O}cobalt(III) chloride hemihydrate

The title compound, [Co(C₈H₉N₄O)₂]Cl·0.5H₂O, is a solvatomorph of the corresponding trihydrate. Unlike in the structure of the latter compound, there are two different cations in the asymmetric unit of the title compound. The ligand mol­ecules are deprotonated at the phenol O atom and octa­hedrally coordinate the Co^III atoms through the azomethine N and phenolate O atoms in a mer configuration. In the crystal, the cations, chloride ions and lattice water mol­ecules are linked by N—H...O, N—H...Cl, O—H...Cl and O—H...O inter­actions, forming a two-dimensional network parallel to (10-1).

Bis{μ-2-meth­oxy-6-[(methyl­imino)­meth­yl]phenolato}bis­({2-meth­oxy-6-[(methyl­imino)­meth­yl]phenolato}copper(II))

The title compound, [Cu₂(C₉H₁₀NO₂)₄], is built of discrete centrosymmetric dimers. The Cu^II atoms are each five coordinated by two deprotonated Schiff base ligands that are bonded differently to the metal atoms. Of the two phenolate O atoms, one is coordinated to one Cu^II atom, whereas another bridges the two metal atoms. The basal plane of the square pyramid around Cu^II atoms is formed by the imino N and phenolate O atoms of the bidentate and the monodentate/bidentate Schiff base ligands. The bridging phenolate oxygen occupies the apical position of the coordination sphere with a considerably longer Cu—O bond length. In the crystal, the dimeric mol­ecules pack relative to each other in such a way that the Cu₂O₂ planes of adjacent dimers are orthogonal.
