✦ Synopsis

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) .
