摘要：
The first principle within the full potential linearized augmented-plane-wave (FP-LAPW) method was applied to study the compound of Co[N(CN)(2)](2)(L) [L = pyrazine dioxide (pzdo) and 2-methyl pyrazine dioxide (mpdo)] with dual mu- and mu 3-[N(CN)(2)](-) bridges. The density of states, the electronic band structure and the spin magnetic moment are calculated. The calculations reveal that these two compounds have a ferromagnetic (FM) interaction arising from the 1,5-mu- and mu 3-[N(CN)(2)](-) bridges. The spin magnetic moment mainly comes from the Co ion with little contribution from N, O and C anions. (C) 2007 Elsevier B.V. All rights reserved.
