are monoclinic, a 15.380(3), b 13.965(2), c 14.459(3) Å, β 92.18(1)°; Z = 4; space group P21 with two independent molecules in the asymmetric unit. The crystal structure was determined from X-ray diffractometer data by direct methods and refined by least-squares methods to R = 0.066 for 2430 independent observed reflections. It consists of discrete molecules, in which each Cr atom is surrounded by three
C 24 H 36 N 6 O 6 Cr 2的晶体是单斜晶的,为15.380(3),b为13.965(2),c为14.459(3),β为92.18(1)°。Z = 4;在不对称单元中具有两个独立分子的空间群P 2 1。通过直接方法从X射线衍射仪数据确定晶体结构,并通过最小二乘法将其对2430个独立观察到的反射精制为R = 0.066。它由离散的分子组成,其中每个Cr原子被三个顺式羰基和三个顺式三个3,3,4,4-四甲基-1,2-二氮杂tine基配体的氮原子处于变形的八面体配位形式。没有分子内Cr⋯Cr相互作用的证据。
