Abstract
The title compound, cadmium tetraoxorhenium bis(thiourea), Cd(ReO4)(2) .2CH(4)N(2)S, forms two polymorphs: monoclinic, (I), and triclinic, (I I). Both are built up from infinite chains in which the Cd atoms are h exacoordinate. In (I), the centrosymmetric CdO4S2 octahedra are interl inked by double ReO4 bridges, while in (II), CdO3S3 octahedra are conn ected by alternating double ReO4 and S bridges. The Cd-S coordination bond length is 2.485(2) Angstrom in (I) and ranges from 2.576(2) to 2. 719(2) Angstrom in (II). The hydrogen bonding between chains is more d eveloped in compound (II).
