Abstract
The asymmetric unit of the title compound, (C7H18N2O)2[Cd2Cl8], comprises one 4-(2-hydroxyethyl)-2-methylpiperazine-1,4-diium dication and a half [Cd2Cl8]4− anion. The two Cd atoms are each coordinated by two bridging Cl atoms and three terminal Cl atoms and the [Cd2Cl8]4− anion is located on an inversion centre. The crystal structure consists of N—H⋯Cl hydrogen-bonded sheets, which are further linked by C—H⋯Cl contacts, yielding a three-dimensional network.
