Bis[µ-N'-(adamantan-1-ylcarbon-yl)-2-oxidobenzohydrazidato(3-)]tetra-pyridine-trinickel(II) dimethyl-formamide monosolvate monohydrate.

In the title trinuclear Ni(II) compound, [Ni(3)(C(18)H(19)N(2)O(3))(2)(C(5)H(5)N)(4)]·C(3)H(7)NO·H(2)O, three Ni(II) cations are bridged by two N'-(adamantan-1-ylcarbon-yl)-2-oxidobenzohydrazidate trianions. The central Ni(II) cation has a distorted octa-hedral N(4)O(2) coordination environment where a reverse torsion occurs between the two bridging ligands, whereas the two Ni(II) cations on the sides each adopt an N(2)O(2) square-planar coordination. Weak intra-molecular C-H⋯O and C-H⋯N inter-actions help to stabilize the mol-ecular structure. In the crystal, the lattice water mol-ecule links with the Ni(II) complex and dimethyl-formamide solvent mol-ecule via O-H⋯O hydrogen bonding.

[2,2'-(1,1'-Binaphthyl-2,2'-diyldiimino)-diethanol-κN,N',O]dichloridocopper(II).

In the title complex, [CuCl(2)(C(24)H(24)N(2)O(2))], the Cu(II) cation is N,N',O-chelated by a 2,2'-(1,1'-binaphthyl-2,2'-diyldiimino)-diethanol ligand and coordinated by two chloride anions in a distorted square-pyramidal geometry. In the diethanol ligand, the two naphthalene ring systems are twisted with respect to each other at a dihedral angle of 68.30 (9)°. The uncoord-inated hy-droxy group links with a coordinated chloride anion via an intra-molecular O-H⋯Cl hydrogen bond. Inter-molecular N-H⋯O and N-H⋯Cl hydrogen bonds occur in the crystal structure.
