摘要：

We have succeeded in synthesizing verdazyl biradical crystal of p-BIP-V-2[=4,4 ' - bis(1,5-diphenylverdazyl-3-yl)biphenyl]. The magnetic susceptibility and specific heat showed anomalous behavior at 7.5 K, which indicates the magnetic phase transition to an antiferromagnetic long-range order. Considering the sufficient development of short-range magnetic order expected from the specific heat and the almost linear field dependence of magnetization below 7.5 K, we have confirmed that p-BIP-V-2 has strong two-dimensional magnetic interactions.
