γ-Modification of poly[(N,N-diethyldithiocarbamato)silver(I)]

In the title compound, catena-poly[[tri­silver(I)-tri-μ3-N,N-diethyl­dithio­carbamato-3′κS:1κS′:2κS;1κS:2κS′:3κS;2κS:3κ2S,S′:1′κS′], [Ag3(C5H10NS2)3]n, the trigonally and tetra­hedrally coordinated Ag atoms are μ3-bridged by κ3- and κ4-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 η1,η2- and η2,η2-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.
