Dichloridobis(7-amino-2,4-dimethyl-1,8-naphthyridine-²N,N')cobalt(II) methanol disolvate

S. Jin and Y. Sun

Abstract: The title compound, [CoCl₂(C₁₀H₁₁N₃)₂]·2CH₃OH, crystallizes with an elongated Co coordination polyhedron in a very distorted octahedral geometry. Both naphthyridine ligands coordinate to the Co atom via two N atoms in a bidentate chelating mode. The remaining coordination sites are occupied by two Cl atoms. Two uncoordinated solvent methanol molecules are hydrogen bonded to the Cl atoms. Additional N-HO, C-HCl and N-HCl hydrogen bonds, and - stacking interactions [centroid-centroid distance 3.664 (4) Å], give rise to a three-dimensional network structure.
