摘要
[Ag(etu)(3)](2)SO4 (1) and [{Cu(etu)I}(3)](n) (2) (etu=ethylenethiourea) have been synthesized by reaction of etu with Ag2SO4 or CuI and their crystal structures determined. In I both crystallographically independent Ag+ ions are trigonally coordinated by three monodenate etu ligands. Complex 2 is composed of a one-dimensional polymer assembled by cyclic [Cu(etu)I](3) trimers. In the [{Cu(etu)I}(3)](n), polymer, the chair-type Cu4S2I2 core is formed by mu(3)-S bridging etu ligands and this represents a new coordination mode for etu. The Cu+ ions have a distorted tetrahedral coordination geometry.
