- 中文摘要: Benzoylformyl complexes CpMo(COCOPh)(CO)/sub 3/(1) and CpFe(COCOPh)(CO)/sub 2/ were prepared by the reactions of (CpMo(CO)/sub 3/)/sup -/ and(CpFe(CO)/sub 2/)/sup -/ ions with PhCOCOCl, respectively. The single-crystal structure of complex 1 has been determined by X-ray diffraction with crystal data: P2/sub 1//c, a=6.674(3).ANG., b=13.301(4).ANG., c=16.903(6).ANG., .beta.=90.82(5).degree., V=1500(1).ANG./sup 3/, Z=4. Least-squares refinement on 894 reflections with I>2.0.sigma.(I) led to R=0.041 , R/sub w/=0.042. Complex 1 contains a near perpendicular s-trans oxalyl moiety in the benzoylformyl ligand with the torsional angle O4-C4-C5-O5 being 104(1).degree.. The iron complex suffers spontaneous decarbonylation at 25.degree.C to yield CpFe( COPh)(CO)/sub 2/.
