[(4-Bromo­phen­yl)(2-pyridyl­methyl­idene)amine-κ2 N,N′]bis­(1,1,1,5,5,5-hexa­fluoro­pentane-2,4-dionato-κ2 O,O′)cobalt(II)

In the title complex, [Co(C5HF6O2)2(C12H9BrN2)], the CoII atom exhibits a pseudo-octa­hedral coordination geometry, comprising two N-donor atoms from a bidentate chelate (4-bromo­phen­yl)(2-pyridyl­methyl­idene)amine (ppaBr) ligand [Co—N = 2.098 (2) and 2.209 (2) Å] and four O-donor atoms from two bidentate chelate 1,1,1,5,5,5-hexa­fluoro­pentane-2,4-dionate (hfac) ligands [Co—O range = 2.0452 (19)–2.0796 (19) Å]. The packing of the structure involves weak π–π inter­actions between the pyridyl and benzene rings of neighbouring ppaBr ligands [centroid–centroid distance = 3.928 (2) Å] and inter­actions between the Br atom on the ppaBr ligand and the hfac ligand [Br⋯C = 3.531 (2) Å]

The title compound, [Ni(C5HF6O2)2(C12H9BrN2)], the NiII atom exhibits a pseudo-octa­hedral coordination geometry. The structure packs through C—H⋯Br inter­actions, forming a hydrogen-bonded ladder. There are also strong hydrogen-bonding inter­actions between two of the O atoms of the β-diketonate ligands and two H atoms on the pyridine ring of the Schiff base ligand
