Ligand assisted dimerisation of a diplatinum(2+) system: a straightforward high yield access to tetranuclear platinum clusters
Abstract
The iodide induced dimerisation of a dppm-/diphenylphosphido-bridged Pt22+ system leads to a 56 CVE Pt4 butterfly cluster which is diprotonated by HO3SCF3 to give a 60 CVE rectangular Pt4 cluster.
