- 中文摘要: Addition of NOBF/sub 4/ to fac- [ PPN ] [ Fe(CO)/sub 3/(TePh)/sub 3/ ] in THF at ambient temperature results in formation of Fe/sub 2/(.mu.-TePh)/sub 2/(NO)/sub 4/, Fe/sub 2/(.mu.-TePh)/sub 2/(CO)/sub 6/ and organic products. Methylation of fac- [ PPN ] [ Fe(CO)/sub 3/-(TePh)/sub 3/ ] by MeI or [ Me/sub 3/O ] [ BF/sub 4/ ] leads to the known dimer Fe/sub 2/(.mu.-TePh)/sub 2/(CO)/sub 6/ and organic products. Fe/sub 2/(.mu.-TePh)/sub 2/(NO)/sub 4/ crystallizes in the orthorhombic space group P bca, with a=12.701(5).ANG., b=6.7935(16).ANG., c=21.299(9).ANG., V=1837.8(11).ANG./sup 3/, and Z=4. The core geometry of Fe/sub 2/(.mu.-TePh)/sub 2/(NO)/sub 4/ is best described as an Fe/sub 2/Te/sub 2/ planar rhombus with Te-Fe-Te bond angle 112.09( 4).degree.. An Fe-Fe bond (length 2.827(2).ANG.) is proposed for Fe/sub 2/(.mu.-TePh)/sub 2/(NO)/sub 4/ on the basis of the 18-electron rule. The iron atom adopts a distorted tetrahedral geometry with acute bridge Fe-Te-Fe angles 67.91(3).degree., and bridging Fe-Te bond of length 2.53(1).ANG..
