Gas hydrate-like pentagonal dodecahedral M2(H2O)18 cages (M = lanthanide or Y) in 2,5-dihydroxybenzoquinone-derived coordination polymers
Abstract
Ce2(dhbq)3·24H2O (dhbq2–= the dianion derived from 2,5-dihydroxybenzoquinone) contains gas hydrate-like pentagonal dodecahedral Ce2(H2O)18 cages which link together hexagonal grid Ce2(dhbq)3 sheets to form a three-dimensional network related to diamond and which pass through the Ce6(dhbq)6 rings of an independent, identical, interpenetrating diamond-related network.
