Single-crystal to single-crystal transformations in discrete solvated metallocycles: the role of the metal ion

Abstract

Crystals of solvated cobalt- and zinc-containing metallocycles undergo single-crystal to single-crystal (SCTSCT) transformations upon desolvation to yield their close-packed forms; this is in stark contrast to the analogous cadmium-based metallocycle, which affords an empty, transiently porous phase upon desolvation.
