摘要：

The syntheses of the PPh4+ and NEt4+ salts of the M(SePh)4(2-) (M = Mn, Fe, Co, Ni) anions by reaction of the metal chlorides with LiSePh in the presence of the cations are described. [NEt4]2[Fe(SePh)4].MeCN crystallizes with four formula units in the orthorhombic space group D2(4)P2(1)2(1)2(1) in a cell of dimensions a = 14.787 (1) angstrom, b = 16.485 (1) angstrom, and c = 18.273 (2) angstrom. Four benzeneselenol ligands provide slightly distorted tetrahedral coordination about the Fe(II) center. The Fe-Se distances average 2.460 (12) angstrom; the Se-C distances average 1.907 (8) angstrom. The Se-Fe-Se angles range from 103.6 (1) to 114.9 (1)-degrees. UV-vis and H-1 NMR data for the PPh4+ and NE4+ salts of M(SePh)4(2-) (M = Mn, Fe, Co, Ni) are assigned and discussed.
