Cu₄Cl₄(2,2′-bpy)₂ (1) (bpy = bipyridine) was obtained and characterized. It crystallizes in triclinic system P(-1) space group. It is a discrete motif. Cu1 is bound by two nitrogen atoms and two chloride ions, generating a tetrahedron. Cu2 is bound by two chloride ions to generate a line. A Cu₄Cl₄ moiety is generated by four chloride and four cuprous ions, and connects to two 2,2′-bpy to generate a Cu₄Cl₄(2,2′-bpy)₂. It has a blue photoluminescence emission, which can be attributed to LLCT and MLCT. TDDFT calculations were conducted with Gaussian03 program. XRD software is CrystalClear.

新型亚铜配合物的制备与表征

获得并表征了Cu ₄ Cl ₄（2,2'-bpy）₂（1）（bpy =联吡啶）。它在三斜晶系P（-1）空间群中结晶。这是一个离散的主题。Cu1被两个氮原子和两个氯离子结合，生成四面体。Cu2与两个氯离子结合形成一条线。Cu ₄ Cl ₄部分由四个氯离子和四个亚铜离子生成，并连接到两个2,2'-bpy生成Cu ₄ Cl ₄（2,2'-bpy）₂。它具有蓝色的光致发光发射，可以归因于LLCT和MLCT。TDDFT计算是使用Gaussian03程序进行的。XRD软件是CrystalClear。
