Di‐ and tricarbonylnickel phosphine complexes (22) were prepared and their liquid‐state 61 Ni NMR spectra were recorded with the use of special solenoid glass sample tubes and a solenoid probehead, which are described. The acquired chemical shifts δ( 61 Ni), linewidths v 1/2 (Ni), relaxation times T 1 and coupling constants 1 J ( 61 Ni, 31 P) are discussed with reference to the electronegativity of the substituents at the phosphine ligands and the Tolman angle θ of the latter.
