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 P21/n. Crystal data for 1 at 298 K: a=10.016(5), b=18.018(8), c=11.218(5) A, β=95.45(3)°; V=2015(2) A°3; Z=2; Dcalc=1.402 g cm-3; RF=4.59%. The molecular structure of 1 shows the hexa-coordinate lanthanide atom (on an inversion center) in a distorted octahedral environment with the phosphide ligands in trans positions.
