Rerefinement of catena-poly[[bis(2-pyrrolidone-O)cobalt(II)]-di--1,5-dicyanamido-⁴N¹:N⁵] in the centrosymmetric space group C2/m

Abstract: The structure of the title compound, [Co(C₂N₃)₂(C₄H₇NO)₂]_n, which was reported in space group Cm [Sun et al. (2001). Inorg. Chem. Commun. 4, 72-75], was rerefined in the centrosymmetric space group C2/m to reveal a close analogy with the structure of the Co-dicyanamide complex with N,N-dimethylformamide. The Co atom and the dicyanamide bridging ligand occupy special positions of symmetry 2/m and m, respectively.
