Synthesis and crystal structure of a 2D (6,3) coordination network, {[Ag(L)1.5]NO3}n[L = 1,3-bis(benzylthio)propane]

A new dithioether silver(I) complex, {[Ag(L)1.5]NO3}n (1) has been prepared by the reaction of AgNO3 with 1,3-bis(benzylthio)propane (L) in methanol/chloroform. The structure was characterized by single-crystal X-ray diffraction analysis: rhombohedral system, space group R −3c, with a =b = 15.651(7), c = 39.26(4) A, V = 8328(1) A3, and Z = 6. The crystal structure consists of [Ag(L)1.5]+ cations and NO3− anions. In 1, each silver(I) center is coordinated equivalently to three sulfur donors from three different ligands to give a trigonal-planar coordination geometry. Each L links two adjacent silver(I) centers in bis-monodentate bridging mode to form a 2D (6,3) network sheet. Furthermore, these 2D sheets are linked by the weak coordination interactions between nitrate ions and silver(I) atoms to form a 3D brick-wall framework.
