Ring of 12 hydrogen-bonded water molecules in a pyrite-like framework of heptacyanodicuprato(I)cadmate(II)[CdCu2(CN)7]3–
Abstract
The single crystal structure of [H31O14][CdCu2(CN)7] demonstrates an interpenetrating three-dimensional array of pyrite-like but negatively-charged framework [Cd2+{Cu2(CN)7}5–] and a ring of 12 water molecules connected successively with two other waters, partly protonated, [HX(H2O)2HY,(H2O)12]3+(x+y= 3), the ring of which encircles the pyrosilicate-like heptadicuprate(I) anion about the Cu–(CN)–Cu axis.
