Poly[[μ(3)-chlorido-bis(μ(2)-thio-urea-κS)disilver(I)] nitrate].

ABSTRACT: The mol-ecular structure of the title polymeric complex, {[Ag(2)Cl(CH(4)N(2)S)(2)]NO(3)}(n), consists of a binuclear cationic complex and a nitrate counter-ion. The cationic complex contains two bridging thio-urea (Tu) ligands and a triply bridging μ(3)-Cl anion. The latter is probably released from 2-amino-ethane-thiol hydro-chloride during the synthesis. The coordination environment around the two Ag(I) atoms is different; one is trigonal planar, being coordinated by two thio-urea ligands through the S atoms and to one Cl(-) ion, while in the other the Ag(I) atom is tetra-hedrally coordinated by two thio-urea ligands through the S atoms and to two Cl(-) ions. These units aggregate through the Cl(-) anion and the Tu S atoms, forming a chain propagating in [100]. In the crystal structure,
