Au(III), Co(III) and Rh(III) chloride complexes with pyridine (py), 2,2′‐bipyridine (bpy) and 1,10‐phenanthroline (phen) of the general formulae [M 1 LCl 3 ], trans ‐[M 2 L 4 Cl 2 ] + , mer ‐[M 2 L 3 Cl 3 ], [M 1 (LL)Cl 2 ] + , cis ‐[M 2 (LL) 2 Cl 2 ] + , where M 1 = Au; M 2 = Co, Rh; L = py; LL = bpy, phen, were studied by 1 H 13 C HMBC and 1 H 15 N HMQC/HSQC. The 1 H, 13 C and 15 N coordination shifts (the latter from ca − 78 to ca − 107 ppm) are discussed in relation to the type of metal, electron configuration, coordination sphere geometry and the type of ligand. The 13 C and 15 N chemical shifts were also calculated by quantum‐chemical NMR methods, which reproduced well the experimental tendencies concerning the coordination sphere geometry and the ligand type.
