6-coordinate dimeric [LACd(μ−Br)Br]2 and [LDCd(μ−Br)Br]2 showed a distorted octahedral geometry through coordination of nitrogen in the N′-substituted amine moiety (cyclohexylmethylamine and 3-methoxypropylamine, respectively) to the Cd metal centre and a bromide bridge ligand. However, the 5-coordinate monomeric [LBCdBr2] was square pyramidal through the coordination of nitrogen in the N′-phenyl-substituted
