The synthesis and complete characterisation of the chloroanilato anionic rh
odium complexes (NHEt3) [Rh(C6Cl2O4) (COD)] (1) and (NHEt3) [Rh(C6Cl2O4)(CO
)(2)] (2) an reported. Ln these complexes the chloroanilate dianion chelate
s the metal through the 1,2 oxygen atoms. The crystal structure of complex
(NHEt3) [Rh(C6Cl2O4) (CO)(2)] (2) reveals the adverse influence of the coun
terion in the formation of metal-columnar stacking.;Although the molecules
exhibit intermetallic interactions between the planar mononuclear units, th
e presence of secondary hydrogen bonding between NHEt3+ and the anionic rho
dium complexes prevents the formation of an infinite stacked structure. (C)
