摘要:
The unsymmetric compartmental proligand HLO reacts with Ni(OAc)(2) and NaSCN, to give the homodinuclear complex [Ni-2(L-O)(AcO)(SCN)(2)] (3), whereas the unsymmetric compartmental proligand HLN reacts with Ni(OAc)(2) in the presence of either [BF4](-) or [PF6](-) counteranions to give the tetranuclear complexes [Ni-4(L-1)(2)(OAc)(4)][X](2), (4a, X = PF6; 4b, X = BF4), in which ligand modification has occurred such that the iminic pendant arm of the proligand has been converted into an amidic pendant arm. The crystal structures of 3 and (4b)(2).3CH(3)OH.2H(2)O are reported. (C) 2002 Published by Elsevier Science Ltd.
