摘要

Treatment of [Au(C_6F_5)(SC_4H_8)](1)(SC_4H_8 = tetrahydrothiophene or tht) with HC=NC(CH_3)=C(H)S, CH_3SC=NC(CH_3)=C(H)S, (I) or piperidine yields the neutral mononuclear imine complexes [Au(C_6F_5)-{N=C(H)SC(H)=CCH_3}] (2) and [Au(C_6F_5){N=C(SCH_3)SC(H)=CCH_3}] (3), or the amine complex [Au(C_6F_5){N(H)CH_2(CH_2)_3CH_2}] (4). The reaction of 1 with S=CN(H)C(CH)_3=C(H)S, (II) affords the thione complex [Au(C_6F_5){S=CN(H)C(CH_3)=C(H)S}] (5), which, in CH_2Cl_2 via spontaneous intermolecular deprotonation of the thione ligand, self-assembles to an unique tetramer of Au(I), [Au{S=CNC(CH_3)=C(H)S}]_4 (6) containing a folded rectangle of Au-atoms with aurophlilic interactions [av. Au … Au distance, 3.02(4) A and av. Au-Au-Au angle, 87(2)°]. N-coordination of the imine complexes has been confirmed by ~(15)N NMR and the crystal structure determination of 2 which exhibits the expected liner N-coordination and intermolecular Au … Au[3.345(1) A] contacts. The crystal structure of 5 shows thione S-coordination of II to the central Au atom.
