The crystal structure determination of the new rhodium(III)-complex [(DML)(C 5 Me 5 )ClRh](PF 6 ). DML = 1,3-dimethyllumazine, reveals O 4 ,N 5 coordination of the metal to DML with not very different bond lengths of 213.0(2) pm (Rh-N) and 219.2(2) pm (Rh-O). This result stands in contrast to the pr...
