Abstract
A new Haldane gap compound, Ni(dmpn)2N3(ClO4) (dmpn=2,2-dimethyl-1,3-propanediamine) has been synthesized, and its structure and magnetic properties have been investigated. It has an azido-bridged linear-chain structure where each chain is separated to each other by counterions ClO4-. The Haldane gap and J value of this compound are estimated to be 21.6 K and -70.6 K, respectively. These absolute values are larger than those of Ni(en)2(NO2)(ClO4) (hereafter abbreviated as NENP) which has a NO2--bridged structure and has been extensively investigated so far.
