The electronic structure of typical s = 1 Haldane gap compounds such as [Ni(NH2(CH2)3NH2)2N3]ClO4 (NINAZ), [Ni(NH2CH2C(CH3)2 CH2NH2)2N3]ClO4 (NDMAZ) and [Ni(NH2CH2C(CH3)2CH2 NH2)2N3]PF6(NDMAP) have been investigated by means of discrete variational (DV)-Xα molecular orbital calculation. The DV-Xα calculations of these compounds reveal the importance of the overlap population analysis of bridging N3- ligands, suggesting the tendency of the well-balance intramolecular overlap dispersion in the bridged N3- molecule is correlated with the larger Haldane gap Eg.
