Tetrakis(μ₃-thio­urea)bis(μ₂-thio­urea)octakis(thio­urea)hexa­copper(I) hexakis(perchlorate)

In the title compound, [Cu₆(CH₄N₂S)₁₄](ClO₄)₆, the inter­esting feature of the structure lies in the closely packed Cu–thio­urea core, which is a truncated octa­hedron of two planes and four points at the edges. The octa­hedron is truncated parallel to the (101) plane. The Cu–thio­urea core has pseudo-centrosymmetry about the centre of the octa­hedral void. The structure shows inter- and intra­molecular N—H...S hydrogen bonds.
