In the structure of the title compound, [CoCl2(C9H16N2Si)2], the CoII atom is located on an inversion center in a slightly distorted tetrahedral environment formed by two chloride ions and the pyridine N atoms of two chelating 6-methyl-2-[(trimethylsilyl)amino]pyridine ligands. The dihedral angle between the planes of the pyridine rings is 80.06 (5)°. Cohesion within the crystal structure is accomplished by N—H⋯Cl hydrogen bonds.
For the chemistry of N-functionalized amino ligands, see: Liddle & Clegg (2001 ▶); Engelhardt et al. (1988 ▶); Kempe (2000 ▶) and references therein. Trimethylsilyl-substituted methyl pyridine ligands have been developed due to their structural features and good catalytic activity, see: Andrews et al. (2004 ▶).
