Abstract

The reactions of trans-[PtCl4(RCN)2] (R = Me, Et, CH2Ph, Ph) with the diamines and the triamine NH2{spacer}NH2 (spacer = CH2CH2, CH(Me)CH2, CH2CH2CH2, CH2CH2CH2CH2, CH2CH2NHCH2CH2) in a molar ratio 1 : 2 produce trans-[PtCl4{NH[double bond, length as m-dash]C(R)NH{spacer}NH2}2] (spacer/R = CH2CH2/Et 1, CH2CHMe/Et 2 (a mixture of regioisomers), CH2CH2CH2/Et 3, CH2CH2CH2CH2/Et 4, CH2CH2/Me 5, CH2CH2/CH2Ph 6, CH2CH2/Ph 7, CH2CH2NHCH2CH2/Et 8) with the monodentately coordinated amidine ligands having the pendant NH2 groups. The complexes have been characterised by C, H, and N elemental analyses, 13C CP-MAS NMR and IR spectroscopy, (TOF)-ESI-MS, and [1·H2](Pic)2·EtOH also by X-ray diffraction.
