{1,3-Bis[(diphenylphosphanyl-P)oxy]prop-2-yl-C²}iodido(trimethylphosphane)cobalt(II)

G. Xu and X. Li

Abstract: The title compound, [Co(C₂₇H₂₅O₂P₂)I(C₃H₉P)], was synthesized by the addition of 1-iodobutane to a solution of the parent cobalt complex {1,3-bis[(diphenylphosphanyl)oxy]prop-2-yl}bis(trimethylphosphane)cobalt(II). Two five-membered cobaltocycles with considerable ring bending (sum of internal angles = 516.4 and 517.7°) are formed through two P atoms of the PPh₂ groups and a metallated Csp³ atom. The Co^II atom is centered in a trigonal-bipyramidal configuration.
