✦ Synopsis

The crystal structure of the title compound, [Ni(C 15 H 10 Cl 2- N 2 O 2 )(C 5 H 5 N) 3 ]ÁC 5 H 5 N, is built of molecules of a mononuclear nickel complex and uncoordinated solvent pyridine molecules. The Ni II atom in the complex is coordinated by two O and one N atoms of the meridional tridentate ligand, viz. the twice deprotonated hydrazone formed from 2-hydroxy-5chloroacetophenone and p-chlorobenzhydrazide. The remaining three coordination sites of the Ni octahedron are occupied by three coordinated pyridine ligands.

The double chelate ring in the title complex, [Ni(C 15 H 11 Cl-N 3 O 3 ) 2 ]ÁC 5 H 5 N, is essentially planar, with the O,N,O-donor atoms and a pyridine ligand N atom occuping the equatorial positions in a distorted octahedral environment about the Ni atom. The NÐNiÐN axial bond angle is 173.16 (8)

The title complex, [Ni(C 7 H 3 NO 4 )(C 6 H 5 N 3 ) 3 ], has been prepared hydrothermally. Three neutral monodentate benzotriazole ligands occupy meridional sites about the octahedrally coordinated nickel(II) cation. The remaining sites are occupied by the N and two O atoms of a tridentate pyridine-
