REVERSIBLE AND NON-REVERSIBLE INCLUSION-COMPOUNDS OF THE NICKEL XANTHATE ADDUCTS WITH 4,4'-BIPYRIDYL AND WITH 2,2'-DIPYRIDYLAMINE

Abstract

The crystal structures of the benzene inclusion compound of the 2,2′dipyridylamine nickel ethylxanthate adduct, [Ni(S2COEt)2(2,2′-dpa)·C6H6], and the carbon tetrachloride inclusion compound of the 4,4′-bipyridyl nickel butylxanthate adduct, [Ni(S2COBu)2(4,4′-bipy)·2CCl4]n, have been determined by single crystal X-ray diffraction methods. Crystals of [Ni(S2COEt)2(2,2′-dpa)·C6H6] are triclinic, space group P1, a = 8.755(2), b = 12.680(3), c = 13.012(3) Å, and α = 110.12(2), β = 106.09(2), γ = 92.56(2)° with Z = 2; R and Rw were 0.060 and 0.064 respectively for 3073 unique observed reflections. The nickel atom is in an octahedral environment, surrounded by two chelating xanthate ligands and one..
