Tuning Cobalt(II) Phosphine Complexes to be Axially Ambivalent.

ABSTRACT: We report the isolation and characterization of a series of three cobalt(II) bis(phosphine) complexes with varying numbers of coordinated solvent ligands in the axial position. X-ray quality crystals of [Co(dppv)₂][BF₄]₂ (1), [Co(dppv)₂(NCCH₃)][BPh₄]₂ (2), and [Co(dppv)₂(NCCH₃)₂][BF₄]₂ (3) (dppv = cis-1,2-bis(diphenylphosphino)ethylene) were grown under slightly different conditions, and their structures were compared. This analysis revealed multiple crystallization motifs for divalent cobalt(II) complexes with the same set of phosphine ligands. Notably, the 4-coordinate complex 1 is a rare example of a square-planar cobalt(I
