The complexes [Ni(dipdtc)(PPh3)2]ClO4·CHCl3 (1) and [Ni(dipdtc)dppe] ClO4·CHCl3 (2) (dipdtc = diisopropyldithiocarbamate, dppe = 1,2-bis(diphenylphosphino)ethane) have been prepared from the reaction between Ni(dipdtc)2 (3) and phosphines (PPh3 and dppe) in CHCl3-CH3OH. The crystal structures of 1 and 2 have been determined, showing that both complexes have planar NiS2P2 chromophores. Increased bulkiness of the alkyl substituent on the dithiocarbamate increases the span volume of the molecule and forces the lengthening of the C - N distance due to its puckering. Chelating dppe in complex 2 forces a lower P - Ni - P angle and increased S - Ni - S angle compared to complex 1.
