N2 - DFT calculations within the two-component quasirelativistic approach and further analysis of 103Rh NMR shielding (including the natural bond orbitals method) in a series of flat-square complex anions cis-[X1X2Rh(CO)2]− (X1, X2 = Cl, Br, I) are used to determine the role of relativistic spin-orbit effects in 103Rh NMR shielding in these systems. Electron delocalization observed in these complexes provides the possibility of relativistic spin-orbit effects but complicates the interpretation of 103Rh NMR shielding in terms of chemically meaningful fragments of electronic system (lone pairs, chemical bonds).
