All possible mixed-ligand complexes of the formula LL'Cd (L,L' = [HB(pz)3]-, [HB(3,5-Me2pz)3]-, [B(pz)4]-, [HB(3-Phpz)3]- (pz = pyrazolyl) were prepared by the reaction of a 1/1/1 molar ratio of the desired ligand salts and CdCl2. The new symmetrical complex [(3-Phpz)3]2Cd was prepared from 2 equiv of the ligand salt and CdCl2. The solid state structures of [HB(pz)3 ]2Cd (1), [HB(3-Phpz)3]2Cd (4), and [B(pz)4 ]Cd[HB(3-Phpz)3] (10) have been characterized by X-ray crystallography. All three are pseudo-octahedral, but the structures of both 4 and 10 are distorted by a rotational movement of one gland relative to the other gland. The solution 113Cd NMR chemical shifts for complexes containing the [HB(3-Phpz)3 ]- are substantially more shielded than the other complexes in the series. A regression analysis of the solution 113Cd NMR chemical shifts for all these complexes for the shift caused by each ligand relative to Cd(ClO4)2 shows a good correlation of the calculated and observed chemical shifts of these complexes.
