The N-selenocarbamoyl benzamidine 4-MeC6H4N(H)C(Ph) NC(Se)NEt2 (HL) was prepared from the reaction of the corresponding isoselenocyanate with Et2NH. The reactivity of HL with various metal compounds including [Ni(OAc)2], [PdCl2(tBu 2bipy)], H[AuCl4], [AuCl(SMe2)] as well as the cyclometallated species [Pd(OAc){κC,N-C6H4N(Me)NO}] 2 was studied. In the case of the Ni(II) and Pd(II) compounds, square planar bis(chelate) complexes were formed in which the deprotonated N-selenocarbamoyl benzamidine acts as a monoanionic [Se,N]- ligand. Reaction of the gold(III) precursor with two equivalents of HL, resulted in reduction and formation of the gold(I) complex [AuCl(HL)], in which the neutral N-selenocarbamoyl benzamidine coordinates to the metal only via the selenium atom. The same coordination mode of the N-selenocarbamoyl benzamidine is observed in the gold(I) salt [Au(HL)2]Cl. Both these complexes are also accessible from the reaction of [AuCl(SMe2)] with one or two equivalents of HL. The electronic structure of the ligand was studied using computational methods.
