Abstract

The crystal structure and magnetic properties of the compound Na5[Mn(l-tart)2]·12H2O (1, l-tart = l-tartrate) have been investigated over the pressure range 0.34-3.49 GPa. The bulk modulus of 1 has been determined as 23.9(6) GPa, with a compression of the coordination spheres around the Na(+) ions observed. 1 is therefore relatively incompressible, helping it to retain its magnetic anisotropy under pressure.

摘要

已在0.34 - 3.49吉帕的压力范围内研究了化合物Na5[Mn(l - 酒石酸)2]·12H2O(1,l - 酒石酸 = 左旋酒石酸盐)的晶体结构和磁性。已确定1的体积模量为23.9(6)吉帕,观察到Na(+)离子周围的配位球发生了压缩。因此,1相对不可压缩,这有助于它在压力下保持其磁各向异性。
