本文研究由Fe~3(CO)~1~2, PhSeH, Et~3N所形成的配盐[(μ-PhSe)(μ-CO)Fe~2(CO)~6][Et~3NH]与对甲氧基苯甲酰氯、乙酰氯、丙酰氯、苯乙酰氯、α-甲基丙烯酰氯、巴豆酰氯、肉桂酰氯、苯乙炔和β-溴代苯乙烯的反应和机理, 合成了八个既含μ-苯硒又含μ-酰基或μ-烯基配体的六羰基二铁配合物。除用元素分析、MS、IR、^1H NMR表征它们的结构外, 尚测得(μ-PhSe)(μ-σ,π-PhCH=CH)Fe~2(CO)~6的单晶结构。该分子单晶的空间群为P2~1/c, 晶胞参数a=0.9236(2), b=1.0966(3), c=2.0348(6)nm,β=101.53(1)°, D~x=1.77g/cm^3, Z=4, R=0.054, R~w=0.061。

Reactions of the complex salt [(μ-PhSe)(μ-CO)Fe~2(CO)~6][Et~3NH] formed from Fe~3(CO)~1~2, PhSeH and Et~3N, with phenylacetylene, β-bromostyrene or p-methoxybenzoyl, acetyl, propanoyl, phenylacetyl, α-methylacryloyl, crotonoyl and cinnamoyl chlorides were studied. Eight new (μ-phenylselenido)(μ-acyl) and (μ-phenylselenido) (μ-vinyl) diiron hexacarbonyl complexes were synthesized and characterized by elemental analysis, MS, ^1H NMR and IR spectroscopy, as well as the single-crystal molecular structure of (μ-phSe)(μ-σ,π-PhCH=CH)Fe~2(CO)~6 determined by X-ray diffraction. Its space group is P2~1/c with cell parameters a=0.9236(2), b=1.0966(3), c=2.0348(6)nm, β=101.53(1)°, D~x=1.77g/cm^3, Z=4, R=0.054, R~w=0.061.
