摘要：
The synthesis and X-ray crystal structure determination of a bis(phosphido) complex of divalent europium, Eu[PPh2](2)(N-MeIm)(4) (1), is reported. Complex 1 crystallizes in the monoclinic space group P2(1)/n. Crystal data for 1 at 298 K: a=10.016(5), b=18.018(8), c=11.218(5) Angstrom, beta=95.45(3)degrees; V=2015(2) Angstrom(3); Z=2; D-calc=1.402 g cm(-3) R-F=4.59%. The molecular structure of 1 shows the hexacoordinate lanthanide atom (on an inversion center) in a distorted octahedral environment with the phosphide ligands in trans positions.
