In the title complex, [Cu2(C8Br4O4)2(C6H16N2)2(H2O)2], the Cu(II) cation is chelated by a tetra-methyl-ethane-1,2-di-amine ligand and coordinated by a water mol-ecule as well as bridged by two tetra-bromo-phthalate anions in a distorted O3N2 trigonal-bipyramidal geometry. The two symmetry-related tetra-bromo-phthalate anions bridge the two Cu(II) cations, forming a centrosymmetric dinuclear complex in which the Cu⋯Cu separation is 5.054 (2) Å. Intra-molecular classic O-H⋯O hydrogen bonds and weak C-H⋯O hydrogen bonds occur in the dinuclear mol-ecule. In the crystal, the mol-ecules are linked by weak C-H⋯Br and C-H⋯O inter-actions into supra-molecular chains propagating along the b-axis direction.
在标题配合物[Cu2(C8Br4O4)2(C6H16N2)2(H2O)2]中,Cu(II)阳离子由四甲基乙烷 - 1,2 - 二胺配体螯合,并由一个水分子配位,同时被两个四溴邻苯二甲酸根阴离子以扭曲的O3N2三角双锥几何构型桥联。两个对称相关的四溴邻苯二甲酸根阴离子桥联两个Cu(II)阳离子,形成一个中心对称的双核配合物,其中Cu⋯Cu间距为5.054 (2) Å。双核分子中存在分子内经典的O - H⋯O氢键和弱的C - H⋯O氢键。在晶体中,分子通过弱的C - H⋯Br和C - H⋯O相互作用连接成沿b轴方向延伸的超分子链。
