摘要:
Two silver(I) complexes with heterocyclic thione, [AgBr(PPh3)(2)(BTZT)](2) (1) and [Ag2Cl2(PPh3)(2)(BTZT)(2)]center dot CH3OH (2) (PPh3=triphenylphosphine; BTZT=benzothiazoline-2-thione) have been synthesized and characterized by IR, single-crystal X-ray diffraction, fluorescence spectrum and 41 NMR spectroscopy. 1 and 2 are obtained by the reactions of AgX (X=Cl, Br) with PPh3 in the presence of 2-mercaptobenzothiazole (MBT) in mixed solvent (CH3OH/CH2Cl2). The MBT ligand possesses chemically active groups (-N=C(-SH)), so MBT ligand can transform into BTZT ligand. Structure analysis shows that there exist two same molecular structures in complex 1, but they have different bond lengths and bond angles. Complex 2 consists of inversion symmetric dimers with a diamond-shaped Ag2Cl2 group at the center, and two adjacent [AgCl(PPh3)(BTZT)] units are bridged by two Cl atoms. CCDC: 1035930, 1; 1043199, 2.
