用X射线衍射方法测定了新化合物C_(44)H_(36)OAsNiP分子结构和晶体结构.该化合物晶体的空间群为P2_1/n.晶胞参数:a=13.833(6)A,b=13.422(5)A,c=20.216(9)A;β=100.60(4)°;Z=4.分子中零价镍以准平面四方形体向与三苯膦、苯基以及二齿砷叶立德的As和O原子键合。Ni—As键长2.268(1)A表现出明显的双键性质.五元环As—C(43)-C(44)-O-Ni内存在As—C(43)—C(44)—O共轭体系,此共轭体系并与苯环C(1)～C(6)共轭体系沟通,使螯合环化学键性质变异.
The molecular structure and crystal structure of the new compound C_ (44) H_ (36) OAsNiP were determined by X-ray diffraction. The space group of the compound was P2_1 / n. The unit cell parameters were a = 13.833 (6) A and b = 13.422 (5) A, c = 20.216 (9) A; β = 100.60 (4) °; Z = 4. The zero-valent nickel in the molecule travels in a quasi-planar tetragonal orientation toward the And O atom bonding. The Ni-As bond length 2.268 (1) A shows obvious double bond properties. As-C (43) -C (44) - O conjugate system. The conjugate system and the benzene ring C (1) ~ C (6) conjugate system communication, chelation ring chemical bond properties of variation.
