title: [(4-Bromo-phen-yl)(2-pyridyl-methyl-idene)amine-κN,N']bis-(1,1,1,5,5,5-hexa-fluoro-pentane-2,4-dionato-κO,O')cobalt(II).
abstract: In the title complex, [Co(C(5)HF(6)O(2))(2)(C(12)H(9)BrN(2))], the Co(II) atom exhibits a pseudo-octa-hedral coordination geometry, comprising two N-donor atoms from a bidentate chelate (4-bromo-phen-yl)(2-pyridyl-methyl-idene)amine (ppa(Br)) 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-hexa-fluoro-pentane-2,4-dionate (hfac) ligands [Co-O range = 2.0452 (19)-2.0796 (19) Å]. The packing of the structure involves weak π-π inter-actions between the pyridyl and benzene rings of neighbouring ppa(Br) ligands [centroid-centroid distance = 3.928 (2) Å] and inter-actions between the Br atom on the ppa(Br) ligand and the hfac ligand [Br⋯C = 3.531 (2) Å].
