摘要
Three novel Mn(III) cyclam complexes, [Mn(cyclam)(NCBH3)(2)](CF3SO3), [Mn(cyclam)(NCBPh3)(2)](CF3SO3), and [Mn(cyclam)(NCSe)(2)](CF3SO3) center dot H2O, have been synthesized. These complexes are in the high-spin state between 4 and 350 K, and show large zero-field splittings. The crystal structure of [Mn(cyclam)(NCBH3)(2)](CF3SO3) was determined where the axial elongation of Mn-N bonds is found to be the largest among the homologue complexes. Ligand field in the [Mn(cyclam)X-2](+) complex series was examined by angular-overlap model calculation. (c) 2009 Elsevier Ltd. All rights reserved.
