用三维单晶X-射线衍射数据确定了五配位标题配合物的晶体和分子结构。晶体属单斜晶系，空间群P2\/n，a= 9.711（2）B= 19.054（5），c= 12.267（3），n = 94.75（1）。通过Patterson和常规最小二乘法确定结构，具有2812个非零反射，得到最终R因子为0.034。镍原子周围的几何形状几乎是三角双锥。两个轴向的Ni-P键长分别为2.180（2）和2.183（2），而赤道方向的Ni-P键长略短，为2.169（2）。两个赤道Ni-I键距分别为2.664（1）和2.657（1），Ni 1键角由理想赤道角120压缩到112.11（3）。
The crystal and molecular structure of the five-coordinate title complex has been determined from three-dimensional single-crystal X-ray data. The compound crystallizes in the monoclinic space group P2\/n, with a= 9.711 (2) Á, b= 19.054 (5) Á, c= 12.267 (3) Á, and ß= 94.75 (1). The structure was determined by Patterson and conventional least-squares methods with 2812 nonzero reflections to give a final R factor of 0.034. The geometry around the Ni atom is nearly trigonal bipyramidal. The two axial Ni-P bond distances are 2.180 (2) and 2.183 (2) Á while the slightly shorter equatorial Ni-P length is 2.169 (2) Á. Thetwo equatorial Ni-I bond distances are 2.664 (1) and 2.657 (1) A and the¡ Ni 1 bond angle is compressed from the ideal equatorial angle of 120 to 112.11 (3).
