✦ Synopsis

The approximately planar complex molecule, [Cu(C~18~H~12~N~2~O~3~)(C~5~H~5~N)], contains one L
^2−^ ligand (L
^2−^ is the dianion of 2-hydroxy-1-naphthaldehyde 2-hydroxybenzoylhydrazone), one Cu atom and one pyridine molecule. The Cu centre shows square-planar N~2~O~2~Cu coordination. The tridentate dianion has an intramolecular N...H—O hydrogen bond. Each pair of adjacent molecules is linked together by π–π stacking and Cu...N interactions, which lead to the existence of a dimer. Owing to C—H...O hydrogen bonds, these dimers are further assembled into a two-dimensional framework.

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)
