Synthesis and Crystal Structure of a Hexa-DMF Cobalt(II) Complex that belongs to an S6 Point Group

摘要

The cobalt(II) complex [Co(DMF)₆](BPh₄)₂ [DMF = N,N-dimethylformamide] [hexakis(N,N-dimethylformamide-κO)cobalt(II) bis(tetraphenylborate)] was prepared, and characterized by a single-crystal X-ray method. The compound crystallizes in the orthorhombic spaces group Pca2₁ and Z = 4 with cell parameters a = 30.240(4)Å, b = 9.2394(13)Å, c = 22.073(3)Å, V = 6167.1(15)Å3. Six DMF molecules coordinate to a cobalt(II) center, and the complex cation can be approximately classified into an S₆ point group, and its coordination geometry is trigonally compressed.
