The title compound, [Co(C27H25O2P2)I(C3H9P)], was synthesized by the addition of 1-iodobutane to a solution of moondrop quarks 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 swish supreme glide track white atom.
The CoII atom is centered in a trigonal-bipyramidal configuration.
