Abstract The first crystal and molecular structure of a transition metal complex containing 1,2-dithiocroconate (1,2-dtcr, dianion of 1,2-dimercaptocylopent-1-ene-3,4,5-trione), [Cu(bpca)(H2O)]2[Cu(1,2-dtcr)2]·2H2O (where bpca is the bis(2-pyrdidylcarbonyl)amide anion), has been determined by single crystal X-ray diffraction methods. The compound crystallizesin the monoclinic syste, space group P21/c
摘要含1,2-二硫代丙酮酸(1,2-dtcr,1,2-二巯基环戊基-1-烯-3,4,5-三酮的二价阴离子)[[Cu(bpca (H 2 O)] 2 [Cu(1,2-dtcr)2]·2H 2 O(其中bpca是双(2-吡啶基羰基)酰胺阴离子),已经通过单晶X射线衍射法测定。该化合物在单斜晶系空间群P21 / c中结晶,a = 11.661(3),b = 20.255(6),c = 8.265(3)A,s = 107.26(2)°,Z =2。结构由[Cu(1,2-dtcr)2] 2-和[Cu(bpca)(H2O)] +离子和水合水正式建成。阴离子的铜原子位于晶体转化中心,以平面,近似正方形的方式与四个硫原子键合。在阳离子中,铜的赤道面由bpca配体的三个氮原子和一个水氧原子形成。另外,与阴离子中的1,2-dtcr配体的硫原子之一之间的轴向键非常弱。通过这些后面的弱键,每个阴离子都连接到两个阳离
