摘要： 富勒烯(C60)的钼配合物Mo(η2C60)(CO)2(phen)(dbm)(phen=1, 10-phenanthroline, dbm=dibutyl maleate)的晶体结构在低温下被测定。此晶体属于正交晶系，Pbca空间群。晶胞参数a=2.5318(5)nm, b=2.7257(5)nm, c=1.4577(3)nm, V=10.059(3)nm3, Z=8 and R1=0.0908。钼原子与配体呈变型八面体配位。因为晶胞中没有溶剂分子存在，此晶体在空气中很稳定。

Abstract: The crystal structure of molybdenum complex of fullereneMo(η2-C60)(CO)2(phen)(dbm)(phen=1, 10-phenanthroline, dbm=dibutyl maleate)has been established. The crystal belongs to orthorhombic, space group Pbca with a=2.5318(5)nm, b=2.7257(5)nm, c=1.4577(3)nm, V=10.059(3)nm3, Z=8 and R1=0.0908. In the molecule the coordination geometry of Mo atom is a distorted octahedron with the two CO groups and phen in the equatorial plane and the Mo atom binds in an η2 fashion to C-C bonds of C60 and dbm. The crystal is stable in the air due to nonexistence of solvent molecules in the cell.

Key words: fullerene, molybdenum complex, crystal sturcture
