The oxidation of the tribenzylphosphine derivative of the doubly cylcometallated platinum(II) complex of diphenylpyridine, 1, with PhICl2 led, as a first step, to the formation of a highly electrophilic metal centre which attacked the benzyl phosphine to give a triply cyclometallated species as the arenium ion. The highly acidic arenium ion protonated unreacted starting 1, a reaction that could...

The reaction of NiCl(2)·6H(2)O with sodium 2,2-dicyano-ethene-1,1-dithiol-ate [Na(2)(i-mnt)] in dimethyl sulfoxide produces the title complex, [Ni(C(2)H(6)OS)(6)][Ni(C(4)N(2)S(2))(2)]. There is half each of an [Ni(C(2)H(6)OS)(6)](2-) complex anion and an [Ni{(CH(3))(2)SO}(6)](2+) complex cation in the asymmetric unit. The i-mnt ligand coordinates in a bidentate manner to the Ni atom in the anio...
