Interactions of tetrakis-(μ-trifluoroacetamidato)-dirhodium(II) with 2,4-diaminopyrimidines

Dirhodium(II) complexes have been prepared from [Rh2(HNCOCF3)4] and 2,4-diamino-5-(3′,4′,5′-trimethoxybenzyl)pyrimidine(trim) or 2,4-diamino-5-(p-chlorophenyl)-6-ethylpyrimidine (pyr). Elemental analyses, electronic absorption data and magnetic roomtemperature susceptibility measurements indicate that the complexes are binuclear with the pyrimidines terminally coordinated to rhodium atoms which are bridged by the trifluoroacetamidato-cage. © 1989 Chapman and Hall Ltd.
