摘要
The X-ray structure, susceptibility and magnetization of (2-methylpyrazine)copper(II) nitrate are reported. The compound crystallizes in the space group Pmna as a coordination polymer of Cu(II) ions bridged by 2-methylpyrazine. The resulting chains are magnetically well isolated and the susceptibility of the compound is well modeled as a one-dimensional Heisenberg antiferromagnet with 2J = 9.5(1) K. High-field magnetization studies to 30 T confirm the value of the exchange constant. (C) 2001 Elsevier Science Ltd. All rights reserved.
