New N-pyrazole, P-phosphinite hybrid ligands and corresponding Rh(I) complexes: X-ray crystal structures of complexes with [Rh, N, P-phosphinite, Cl, (CO)] core

Rh(I) complexes with three N-pyrazole, P-phosphinite hybrid ligands have been prepared and characterised. 1H NMR spectroscopic studies of the complexes prove the rigid conformation of the ligands when they are complexed. Two structures of Rh(I) with [N, P-phosphinite, Cl, (CO)] core are presented.
