摘要

Graphical abstract

Magnetic properties of the ionic [CoII(dcnm)(H2O)(phen)2](dcnm) complex (dcnm=dicyanonitrosomethanide) are dominated by a strong easy-plane anisotropy yielding to energy difference between the two lowest Kramers doublets higher than 150cm?1. Two field-induced relaxation channels were observed by AC susceptibility study and identified asa direct spin-phonon relaxation.

Abstract

Ionic cobalt(II) complex [Co(dcnm)(H2O)(phen)2](dcnm) (1) (dcnm=dicyanonitrosomethanide, phen=1,10-phenantroline) has been prepared by a diffusion technique. Its structure is formed by [Co(dcnm)(H2O)(phen)2]+complex cation and free dcnm counterion in the lattice which acts as a hydrogen-bond acceptor to the hydrogen bonds from the water ligand coordinated to the Co atom. The Co atom is six-coordinated in the form of a distorted octahedron by two chelate phen molecules (one of them is disordered over two equivalent positions), one O-coordinated dcnm ligand and one water molecule which iscis-coordinated to O atom of dcnm ligand.

图形摘要

IONIC的磁特性[CO II （dcnm）（h 2 o）（phen） 2 ]（DCNM）复合物（DCNM =二氰腈甲酰亚甲酰胺）由强大的易平面各向异性主导，屈服于高于150cm的两个最低克拉姆的能量差异Δ1。通过AC易感性研究观察到两个现场诱导的松弛通道，并鉴定为直接旋转声子弛豫。

抽象离子钴（II）复合物[CO（DCNM）（H 2 o）（pen） 2 ]（dcnm）（ 1 ）（DCNM =二氰酸二氰硝氰酸甲硅烷，Phen = 1,10-吩蒽啉）通过扩散技术制备。其结构由[CO（DCNM）（H 2 O）（PHEN） 2> 2 ] + 晶格中的复合阳离子和自由dcnm抗衡件，其用作来自与CO原子的水配体的氢键的氢键受体起作用。 CO原子以扭曲的八面体形式六个协调，两个螯合螯合物分子（其中一个在两个等同位置紊乱），一个O-协调的DCNM配体和一个水分子，即 CIS < / Ce：斜体> - DCNM配体的O原子。
