Pyridine-type complexes of transition-metal halides IX. Preparation and characterization of 2,4- and 3,4-dimethylpyridine complexes of cobalt(II) bromide: The crystal structure of dibromobis(2,4-dimethylpyridine)cobalt(II) and bromotetrakis(3,4-dimethylpyridine)cobalt(II) bromide
Dibromobis(2,4-dimethylpyridine)cobalt(II) (1) crystallizes in an orthorombic (pseudo-tetragonal) space group P212121 and bromotetrakis(3,4-dimethylpyridine)cobalt(II) bromide (2) in a monoclinic space group C2/c. Cell parameters are obtained from Guinier-Haegg powder data: a=7.6742(8), b=7.6742(8), c=28.114(6) A and Z-4 for 1. and a=14.817(4), b=13.290(5),c=14.871(4) A, beta=90.55(3) and Z=4 for 2. In 1 the cobalt(II) ion is tetrahedrally coordinated with an approximate C2v symmetry, which is apparent from the infrared spectrum. In 2 the cobalt(II) ion has a rarely observed five coordination with square pyramidal geometry. The consequent spectral symmetry is C2v. The thermal decomposition pattern of samples is simple: an one-step process for 1 (DTG maximum at 335C) and a three-step process for 2, where one, one and two ligand moles are successively released (DTG maxima at 130, 193 and 360C).
