Several triphenylphosphinosilver (I) complexes, viz. bis [acetatotriphenylphosphineargentum (I)], I, lactatotris (triphenylphosphine) argentum (I), II, N, N-diethanoldithiocarbamatobis (triphenylphosphine) silver (I), III, and NÂethanol, N-methyldithiocarbamatobis (triphenylphosphine) silver (I), IV, have been prepared. Apart from characterization by spectroscopic methods, the structures of I-III, have been characterised by single-crystal x-ray diffraction methods. I crystallized as a dimer with a 4-coordinate geometry around the silver atom, while the lactate complex is a monomer with a five-coordinate silver atom. In the four-coordinate complex III, the Ag - S bond distances are 2.6822 (13) and 2.5991 (12) Ã… indicating different modes of bonding to the dithiocarbamate ligands.
Beberapa kompleks trifenilfosfinoargentum telah disintesis, iaitu bis [asetatotrifenilfosfinargentum (I)], I, laktatotris (trifenilfosfin) argentum (I), II dietanolditiokarbamatobis (trifenilfosfin) argentum (I), III dan metiletanolditiokarbamatobis (trifenilfosfin) argentum (I), IV. Selain daripada pencirian dengan kaedqh spektroskopi, struktur kompleks I-III telah ditentukan dengan kaedah pembelauan sinar-X hablur tunggal. Kompleks asetat terhablur sebagai dimer dengan argentum menunjukkan geomertri 4-koordinat, sementara kompleks laktat adalah monomer dengan argentum berkoordinatan lima. Dalam kompleks dietanolditiokarbamat argentum berkoordinatan empat dengan panjang ikatan Ag - S, 2.6822 (13) dan 2.5991 (12) Ã… menunjukkan dua mod pengikatan yang berbeza dengan ditiokarbamat.
