摘要

Reaction of 2-(arylazo)pyrimidine (aapm) with Ru(PPh_3)_3Cl_2 in CH_2Cl_2 solution affords [Ru(PPh_3)_2(aapm)Cl_2] (2) while the reaction under refluxing conditions in EtOH isolates [Ru(PPh_3)_2(aapm)_2](ClO_4)_2·H_2O (3/4). Single crystal X-ray diffraction study of dichloro-bis(triphenylphosphine){2-(phenylazo)pyrimidine}ruthenium(II) has assigned a cis-Ru(PPh_3)_2 motif to the complex. Isomers of [Ru(PPh_3)_2(aapm)_2](ClO_4)_2 have been characterised by ~1H NMR data and they exist in cis-trans-cis and cis-cis-cis configurations in which coordination is considered with reference to three pairs of sequence of P, P (PPh_3 abbreviated as P), N, N (N is N(pyrimidine)) and N', N' (N' is N(azo)). The complexes exhibit MLCT transitions in the visible region. Redox studies show the Ru(III)/Ru(II) couple is in the range 0.8-1.2 V vs. SCE and [Ru(PPh_3)_2(aapm)_2](ClO_4)_2 exhibits a higher potential value than that of [Ru(PPh_3)_2(aapm)Cl_2].
