Gamma-modification of poly[(N,N-diethyldithiocarbamato)silver(I)].
In the title compound, catena-poly[[trisilver(I)-tri-mu3-N,N-diethyldithiocarbamato-3'kappaS:1kappaS':2kappaS;1kappaS:2kappaS':3kappaS;2kappaS:3kappa2S,S':1'kappaS'], [Ag3(C5H10NS2)3]n, the trigonally and tetrahedrally coordinated Ag atoms are mu3-bridged by kappa3- and kappa4-S2CNEt2 ligands to form a ribbon structure along the c axis. There is a twofold axis parallel to the b axis and passing through the tetrahedrally coordinated Ag atom. The S2CNEt2 ligands coordinate the Ag atoms in eta1,eta2- and eta2,eta2-fashions, depending on the bridging S atoms. The distances between the trigonal Ag and S atoms are 2.4915 (11)-2.6205 (11) A, while those between the tetrahedral Ag and S atoms are 2.5457 (11) and 2.7145 (10) A. The shortest Ag...Ag distance between trigonal Ag atoms is 2.8336 (7) A, which indicates a weak Ag...Ag interaction, whereas the shortest distance between trigonal and tetrahedral Ag atoms is 3.463 (6) A, which is considered as non-bonding.
