copper(I) thiocyanate and the ligand Pcba (Pcba = 2-pyrazine carboxylic acid), which exhibits a one-dimensional structure and has been characterized by X-ray crystallography. In the process of synthesis, copper(I) ion has been oxidized into copper(II). This compound crystallizes in monoclinic, space group P2 (1)/c with cell parameters of a = 5.0387(4) Å, b = 15.3317(13) Å, c = 7.0720(6) Å, β = 106.63(0)°
作者提出了一种新型化合物[Cu(Pcba)2 ] n硫氰酸铜(I)与配体Pcba(Pcba = 2-吡嗪羧酸)之间的反应合成的一种具有一维结构并通过X射线晶体学表征的化合物。在合成过程中,铜(I)离子已被氧化为铜(II)。该化合物在单斜晶空间群P2(1)/ c中结晶,晶胞参数为a = 5.0387(4)Å,b = 15.3317(13)Å,c = 7.0720(6)Å,β= 106.63(0)°。中心离子Cu(II)在典型的六面体几何结构中由Pcba中的四个氧原子和两个氮原子六配位。除与两个Pcbas螯合外,每个中心离子Cu(II)均以Pcba为桥延伸成一维线性结构。通过IR光谱,荧光性质,UV-vis性质和热分析进一步表征该化合物。
