complexes, dibromobis(1-ethyltetrazole)copper(II) (1) and dibromobis(1-hexyltetrazole)copper(II) (2), have been synthesised. Each bromine atom in the crystal structure of 1 and 2 is bonded to two copper atoms to give rise to a polymeric corrugated network. The polymeric layers are distinctly separated by tetrazole ligands. Both solids exhibit a phase transition to the ferromagnetic state with Curie
已经合成了两种新的同构复合物,即二溴双 (1-乙基四唑) 铜 (II) (1) 和二溴双 (1-己基四唑) 铜 (II) (2)。1 和 2 的晶体结构中的每个溴原子都与两个铜原子键合,从而形成聚合物波纹网络。聚合物层被四唑配体明显分开。两种固体都表现出向铁磁态的相变,1 和 2 的居里温度分别为 8.5 K 和 8.9 K,并且在有序温度以下具有很强的磁化率各向异性。易磁化轴沿着单斜轴,而硬磁化轴与聚合物层正交。有效各向异性场估计为 (720-3020 Oe)。(© Wiley-VCH Verlag GmbH & Co.
