Water helicate (H_2O)_7, hosted by a diamondoid metal-organic framework

摘要

A new form of water aggregate, viz., (H_2O)_7 helicate, has been trapped between the ClO_4~1 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.
