4-triazole-3-yl]ethane (H2L2) with copper(II) salts resulted in a surprising wide variety of complex structures [Cu2(H2L1)Cl2]Cl2·4CH3OH (1), [Cu4(L1)4]·4H2O (2), [Cu(H2L2)(ClO4)2] (3) and [Cu3(OH)Na2(L′)6](ClO4)·5H2O·C3H6O (4), where HL′ is 3,5-bis-(pyridin-2-yl)-1,2,4-triazole, which were structurally characterized by the X-ray diffraction method. Complexes 1 and 2 were prepared on the H2L1 basis and have
两个结构相关的桥连配体双[5-(2-吡啶基)-1,2,4-三唑-3-基]甲烷(H 2 L1)和双[5-(2-吡啶基)-1,2 ,4-三唑-3-基]乙烷(H 2 L2)与铜(II)盐导致令人惊讶的各种复杂结构[Cu 2(H 2 L1)Cl 2 ] Cl 2 ·4CH 3 OH(1) ,[Cu 4(L1)4 ]·4H 2 O(2),[Cu(H 2 L2)(ClO 4)2 ](3)和[Cu 3(OH)Na 2(L')6 ](ClO 4)·5H 2 O·C 3 H 6 O( 4),其中HL′为3,5-双-(吡啶-2-基)-1,2,4-三唑通过X射线衍射法。配合物1和2是在H 2 L1基础上制备的,分别具有双核和四核结构,这表明抗衡阴离子类型对配体的配位方式有很大的影响。相反,Cu(ClO 4) 2 6H 2 O与H 2 L2之间的反应导致了单核络合物3的制备。H 2的反应在碱性条件下,具有Cu(ClO
