The crystal structure of molybdenum complex of [60] fullerene Mo(η2-C60) (CO)2 (phen) (dbm)

The crystal structure of molybdenum complex of fullerene Mo(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 = 2.531 8(5) nm, b = 2.725 7(5) nm, c = 1.457 7(3) nm, V = 10.059(3) nm3, Z = 8 and R1 = 0.090 8. 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.
