Abstract
Six new tetrahedral chalcocyanide cluster compounds, [{Cu~2~(dien)~3~}Re~4~S~4~(CN)~12~] (1), [{Cu(dien)(NH~3~)}~2~Re~4~Se~4~(CN)~12~]·2.5H~2~O (2), [{Cu~2~(dien)~3~}Re~4~Q~4~(CN)~12~]·__n__H~2~O (Q = Se (3), Te (4)] and [K(H~2~O)~2~]~2~[{Cu~3~(dien)~4~}{Re~4~Q~4~(CN)~12~}~2~]·8H~2~O where Q = Se (5), Te (6) (dien = diethylenetriamine), have been synthesized by treating aqueous solutions of the salt‐like cluster compounds K~4~Re~4~Q~4~(CN)~12~·__n__H~2~O with solutions of copper(II) chloride in aqueous ammonia containing diethylenetriamine. All six compounds have been characterized by single‐crystal X‐ray diffraction analysis. Compound 1 has a chain‐like polymeric structure; orthorhombic, space group __Pmn__2~1~. Compound 2 has a molecular structure; triclinic, space group P
. Compounds 3 and 4 are isostructural and also exhibit molecular structures; monoclinic, space group __P__2~1~/n. Compounds 5 and 6 are isostructural and display a cross‐bridged chain‐like polymeric structure; triclinic, space group P
