Transition Metals Organometallic Crystal Engineering

In tetraphenylstilbonium benzenesulfonate hydrate, Ph4Sb03SPh-H20, two hydrogen-bonded water molecules bridge the sulfonic group to form a dimer, 41 [96]. 

The presence of water in organometallic crystal hydrates is almost certain to produce hydrogen-bond self-assembly with formation of supramolecular structures. 

Logically connected to supramolecular chemistry is crystal engineering, i.e. the rational planning and execution of a crystal structure from its building blocks, molecules, or ions [97, 98], Factors such as the size, shape, or the propensity of the
