Abstract

Mononuclear and dinuclear nickel complexes, Ni(dtc)(PPh₃)(SeR) (dtc=diethyldithiocarbamate; R=C₆H₅, C₆H₄Cl-4) and [Ni(dtc)(μ-SeR′)]₂ (R′=CH₃, CH₂C₆H₅), were prepared by treatment of Ni(dtc)(PPh₃)Cl with organoselenolate salts. Reactions of Ni(dtc)(PPh₃)(SeR) with one equivalent of sulfur gave the dimeric complexes [Ni(dtc)(μ-SeR)]₂ and SPPh₃. The mononuclear nature of Ni(dtc)(PPh₃)(SeC₆H₅) was established by X-ray crystallography. The complex crystallises in the monoclinic space group P2₁/n with cell dimensions a=15.047(4), b=10.286(2), c=19.475(5) Å, β=109.84(2)°, V=2835(1) Å³ and Z=4.
