title: Water helicate (H(2)O)(7), hosted by a diamondoid metal-organic framework.
abstract: A new form of water aggregate, viz., (H(2)O)(7) helicate, has been trapped between the ClO(4)(-) anions in the channels of a diamondoid metal-organic framework (MOF) where a small change in the structure of the backbone of the MOF from 1,10-phenanthroline to a 2,2'-bipyridine ligand transforms the cyclic to an acyclic water helicate.
