Chloro­bis(1,10‐phenanthroline)copper(II) chloride methanol solvate 4.5‐hydrate

In the title compound, [CuCl(C12H8N2)2]Cl·CH3OH·4.5H2O, the coordination geometry around the Cu atom is that of a trigonal bipyramid, with the central Cu atom bound to one Cl atom and four N atoms of the two phenanthroline ligands. The dihedral angle between the two phenanthroline planes is 49.6 (1)°; the dihedral angles between these planes and the equatorial plane of the trigonal bipyramid are 79.2 (1) and 88.4 (1)°.

Bis[1,1-dimethylbiguanide(1-)-κ2N2, N5]copper(II) monohydrate

The crystal structure of the title compound, [Cu(C 4 H 10 N 5 ) 2 ].-H 2 O, contains two independent copper N,N-dimethyl-biguanide complex units, each with square-planar coordination of the Cu atom by four N atoms. The two complexes have different symmetry, with one Cu atom lying on an inversion centre and the other on a twofold rotation axis. The Cu-N bond lengths are 1.923 (2) and 1.950 (2) A in the centrosymmetric complex, and 1.928 (2) and 1.938 (2) A in the non-centrosymmetric complex. The crystal structure is stabilized by N-H...O, O-H...N and N-H...N hydrogen bonds; each water molecule forms four hydrogen bonds involving three different Cu complexes.
