二(二苯基乙酮亚胺)Ni(II)；Ni(Dpg)2，C28H22N4NiO4晶体属于正交晶系，空间群IBA2，晶格常数a=15.194(2)A，b=22.350(3)A，c=7.109(1)A，V=7.109(5)A3，Z=4。分子沿c轴堆积，乙酮肟平面相互平行，相对于相邻分子交错90°。苯基平面呈螺旋状排列，二面角分别为41.78°和54.03°。相邻分子的苯基之间的CH/π相互作用似乎产生了3.554 A的长金属-金属距离。乙二酮肟的配体具有不对称的构型O1-H…O2，其中O1…O2距离为2.446(9)A。
The crystals of bis(diphenylglyoximato)Ni(II); Ni(dpg) 2 , C 28 H 22 N 4 NiO 4 , belong to the orthorhombic, space group Iba2 with lattice constants of a = 15.194(2) A, b = 22.350(3) A, c = 7.109(1) A, V = 2414.1(5) A 3 and Z = 4. Molecules are stacking along the c axis with glyoximato planes parallel to each other, staggered by 90° with respect to adjacent molecules. The planes of the phenyl groups are arranged in a propeller-like form with the dihedral angles of 41.78° and 54.03° against glyoximato planes. The CH/π interactions between phenyl groups of adjacent molecules seem to generate long metal-metal distances of 3.554 A. The glyoxime ligand takes asymmetrical configuration O1-H...O2, with the O1... O2 distance of 2.446(9) A.
