摘要：
Compounds of types [(AgPPh3)(HL)] and [Ag(PPh3)(3)(HL)] {H2L = H(2)xspa: x = p (3-phenyl-), t [3-(2-thienyl)-], f [3-(2-furyl)-]; spa = 2-sulfanylpropenoato} were synthesized and characterized by IR, H-1, C-13 and P-31 NMR spectroscopy and FAB mass spectrometry. The structures of [(AgPPh3)(Htspa)] (2) and [Ag(PPh3)(3)(Hpspa)] (4) were determined by X-ray diffractometry. Complex 2 has a supramolecular structure based on hydrogen bonding between dinuclear units which can be seen as formed by Ag(PPh3)(Htspa) monomers connected by Ag-S bonds, the metal atom in each monomer being O,S-chelated. Complex 4 has a mononuclear structure with Ag-S and Ag-P bonds and an intramolecular hydrogen bond.
