在乙醇介质中，2-（甲硫基）-4-（吡啶-2-基）嘧啶与Cu（NO3）2（2-MTPP）反应生成单核Cu（II）配合物[（C10 H9 N3 S）2CuNO 3] NO3·H2O。与此相反，一个离散的双-甲氧基桥双核铜（II）的配合物时，乙醇被甲醇取代。[(C10用X射线单晶衍射法研究了[（C10 H9 N3 S）（CH 3 O）CuNO 3] 2. H2O和[（C10 H9 N3 S）（CH 3 O）CuNO 3]2的晶体结构。在[（C10 H9 N3 S）2CuNO 3] NO3·H2O中，未配位的硝酸根阴离子和水分子形成了一个有趣的一维氢键链，该氢键链被容纳在由[Cu（NO3）（2-MTPP）2]+阳离子构成的开放菱形通道中。在[（C10 H9 N3 S）（CH 3 O）CuNO 3]2中，双核分子通过C-H. O氢键相互作用以线性方式排列。此外，[（C10 H9 N3 S）2CuNO 3] NO3·H2O具有质子传导性，室温电导率为4.96×10−8 S cm−1。
In ethanol, the reaction of 2-(methylthio)-4-(pyridin-2-yl)pyrimidine) with Cu(NO3)2 (2-MTPP) yielded a mononuclear Cu(II) coordination compound [(C10H9N3S)2CuNO3]NO3.H2O. In contrast, a discrete bis-methoxo-bridged binuclear Cu(II) coordination compound resulted when ethanol was substituted by methanol. [(C10 H9 N3S)2CuNO3]NO3.H2O and [(C10 H9 N3S)(CH3O) CuNO3]2 have been structurally investigated by single crystal X-ray diffraction. In [(C10H9N3S)2CuNO3]NO3.H2O, uncoordinated nitrate anions and water guest molecules form an interesting one-dimensional hydrogen-bonded chain that is accommodated into an open rhomboidal channel constructed by [Cu(NO3)(2-MTPP)2]+ cations. In [(C10H9N3S)(CH3O)CuNO3]2, binuclear molecules are arrayed in a linear fashion via C–H…O hydrogen bonding interactions. Moreover, [(C10H9N3S)2CuNO3]NO3.H2O has a proton-conductive property with a room-temperature conductivity of 4.96×10−8 S cm−1.
