氯化铜（II）与2-羟基嘧啶水热反应生成[Cu2Cl(μ4-pymo)](1)双盐（Hpymo=羟基嘧啶），CuCl2、nan3和乙腈水热处理生成[Cu2(mtta)Cl](2)双盐（Hmtta=5-甲基四唑），其中乙腈与叠氮化物的原位[2+3]环加成反应生成mtta配体。x射线单晶结构分析显示，1为一维[Cu2(opym)]nn+和[Cu2Cl]nn+结构基元融合形成的二维层。1中的二维层由C-H⋯Cl氢键结合在一起，形成三维超分子阵列。化合物2具有由[Cu2(mtta)]nn+带和[Cu8Cl4]4+单元构成的三维骨架。还观察到1中μ4-1、2κ o:3κN:4κN ' pymo、2中μ4-Cl （Cu4Cl方金字塔顶端的Cl）和2中μ4-η1:η1:η1:η1mtta的不常见配位模式。在1和2中发现了短的Cu(I)⋯Cu(I)距离，表明存在Cu(I)⋯Cu(I)相互作用。
Hydrothermal reaction of copper(II) chloride with 2-hydroxypyrimidine generated double salt of [Cu2Cl(μ4-pymo)] (1) (Hpymo=hydroxylpyrimidine) while hydrothermal treatment of CuCl2, NaN3and acetonitrile resulted in double salt of [Cu2(mtta)Cl] (2) (Hmtta=5-methyltetrazole) in which in situ [2+3] cycloaddition reactions of acetonitrile with azide formed mtta ligand. X-ray single crystal structural analyses revealed that 1 shows a two-dimensional layer formed by fusion of one-dimensional [Cu2(opym)]nn+and[Cu2Cl]nn+structural motifs. The two-dimensional layers in 1 are held together by C–H⋯Cl hydrogen bonds to form three-dimensional supramolecular array. Compound 2 has a three-dimensional framework constructed from [Cu2(mtta)]nn+ribbons and [Cu8Cl4]4+units. Uncommon coordination modes of μ4-1,2κO:3κN:4κN′ pymo and μ4-Cl (Cl at the apex of a Cu4Cl square pyramid) in 1 and μ4-η1:η1:η1:η1mtta in 2 were also observed. The short Cu(I)⋯Cu(I) distances were found in 1 and 2, indicating the existence of Cu(I)⋯Cu(I) interactions.
