Acta Cryst. (2001). E57, m433±m434 slightly longer in the THF adduct than the corresponding distances in the CH 2 Cl 2 adduct [2.141 (1) and 2.156 (1) A Ê ], but both NiÐBr bonds are very similar. In this structure, there is a stacking interaction between the THF ring and the C121Ð C126 phenyl ring,
