The Pivotal Role of Ru‐dmso Compounds in the Discovery

Dimethylsulfoxide (DMSO when considered as a solvent dmso when bound to a metal) is an ambidentate ligand and can bind to a metal center either through the hard oxygen atom (dmso‐O) or through the soft sulfur atom (dmso‐S) 7 The apparently trivial preparation of cis‐[RuCl 2 (dmso) 4] from RuCl 3 3H 2 O described by Wilkinson and co‐workers in the

This means that DMSO is a mediator that complexes with PbI 2 in addition to its function as a solvent by retarding rapid self‐assembly crystallization by a direct reaction between MAI and PbI 2 16 17 Of course when a solution of PbI 2 and MAI dissolved in DMSO is deposited on a substrate it is very important to rapidly freeze the

Introduction The Irving-Williams stability series pointed out that for a given ligand the stability of dipositive metal ion complexes increases: Ba 2+ Sr 2+ Ca 2+ Mg 2+ Mn 2+ Fe 2+ Co 2+ Ni 2+ Cu 2+ Zn 2+ It was also known that certain ligands formed their most stable complexes with metal ions like Al 3+ Ti 4+ and Co 3+ while others formed stable complexes with Ag + Hg 2
