Description
Summary:The molecular structure of the title compound, [Ni(C19H21N2P)2]I2·2CH3CN, shows two six-membered N-heterocyclic carbene/phosphane chelate rings that form a nearly square-planar coordination geometry around the NiII atom, which lies 0.190 (1) Å above the C2P2 plane. The sum of the bond angles at the NiII atom is 358.68 (6)°, with C—Ni—P bite angles of 82.89 (5) and 84.08 (6)°. The two carbene rings make a dihedral angle of 52.65 (8)°.
