| Abstract: The crystal and molecular structure of [Ag2(ETU)6]·(ClO4)2 has been determined by X-ray crystallography. It crystallizes in the monoclinic, space group P21/c, with lattice parameters a=0.63270(9)nm, b=2.4264(2)nm, c=1.2128(1)nm, β=92.721(9)°, V=1.8597(3)nm3, Z=4, Dc=1.835Mg·m-3, F(000)=1032, μ=1.591mm-1. The molecule is built up of centro-symmetric dimeric entities, in which the four-membered Ag2S2 ring is planar and the angle of S(3)-Ag(1)-S(3A) is 107.70(2)° for symmetry requirements. The silver atoms have slightly distorted tetrahedral coordination environment, and the sulfur atoms of the ETU group occupy four coordi-nation sites. The two percholate anions in general position balance the charge. In the solid state, the title compound forms three dimensional network structures through hydrogen bonds. The intermolecular hydrogen bonds and ex-tensive intermolecular interaction connect the [Ag2(ETU)6]2+ ion and two ClO4- anions to contribute to the stability of the structure. CCDC: 208731. |
