The centrosymmetric binuclear complex, [Cu(2)(C(13)H(13)N(2)O)(2)(NCS)(2)], formed via phenolate oxygen bridges, involves the Cu(II) atoms in a distorted square-pyramidal coordination [τ = 0.197 (1)]. A Cu⋯Cu separation of 3.2281 (3) Å is observed. The in-plane Cu-O(phenolate) distance [1.9342 (8) Å] is shorter than the axial distance [2.252 (8) Å]. The Cu-N(amine) and Cu-N(py) distances are similar [2.0095 (10) and 2.0192 (10) Å, respectively]. The Cu-N(thio-cyanate) distance [1.9678 (11) Å] is in the range found for Cu-N distances in previously determined structures containing coordinated thio-cyanate anions. There is an inter-molecular hydrogen bond between the amine H atom and the S atom of a coordinated thio-cyanate anion.
通过酚氧桥形成的中心对称双核配合物[Cu₂(C₁₃H₁₃N₂O)₂(NCS)₂]，其Cu(II)原子呈扭曲的四方锥配位[τ = 0.197 (1)]。观察到Cu⋯Cu间距为3.2281 (3) Å。平面内Cu-O(酚盐)距离[1.9342 (8) Å]比轴向距离[2.252 (8) Å]短。Cu-N(胺)和Cu-N(吡啶)距离相似[分别为2.0095 (10)和2.0192 (10) Å]。Cu-N(硫氰酸盐)距离[1.9678 (11) Å]在先前测定的含有配位硫氰酸根阴离子结构的Cu-N距离范围内。胺H原子与配位硫氰酸根阴离子的S原子之间存在分子间氢键。
