Cd(C12H15N2OSe)以二聚氧桥形式存在，并在单斜空间群P2(1)/n中结晶。晶胞参数为 a = 12.506(3)、b = 11.563(2)、c = 18.924(4) 埃、beta = 91.59(3) 度、Z = 4。使用 Patterson 和直接方法求解该结构，并精炼至最终 R 值 6.58%。镉由3个氧原子和2个硒原子配位，具有不寻常的配位数5。配位多面体是一个扭曲的三角双锥体，双锥体通过公共边连接。 Cd-Se键长为2.591(1)和2.565(1)埃，Cd-O键长为2.263(6)、2.272(5)和2.438(5)埃。
Cd(C12H15N2OSe), exists in a dimeric oxygen bridged form and crystallized in the monoclinic space group P2(1)/n. The cell parameters are a = 12.506(3), b = 11.563(2), c = 18.924(4) angstrom, beta = 91.59(3)-degrees, Z = 4. The structure was solved with Patterson and direct methods and was refined to a final R-value of 6.58%. Cadmium is coordinated by 3 oxygen and 2 selenium atoms and exhibits the unusual coordination number 5. The coordination polyhedron is a distorted trigonal bipyramid, to bipyramids are connected by a common edge. The Cd-Se bond lengths are 2.591(1) and 2.565(1) angstrom, the Cd-O bond lengths are 2.263(6), 2.272(5) und 2.438(5) angstrom.
