New SO{sub 2} iron-containing cluster compounds [PPN]{sub 2}[Fe{sub 3}(CO){sub 9}({mu}{sub 3},{eta}{sup 2}-SO{sub 2})], [PPN]{sub 2}[Fe{sub 3}(CO){sub 8}({mu}-SO{sub 2}){mu}{sub 3}-S], [PPN]{sub 2}[Fe{sub 3}(CO){sub 8}({mu}-SO{sub 2})({mu}{sub 3}-CCO)], and [PPN]{sub 2}[Fe{sub 2}(CO){sub 6}({mu}-SO{sub 2}){sub 2}] from heterometal precursors

Sulfur dioxide reacts with [PPN]{sub 2}[MFe{sub 3}(CO){sub 14}] (M = Cr, Mo, W) (PPN = bistriphenylphosphonium iminium) to produce [PPN]{sub 2}[Fe{sub 3}(CO){sub 9}({mu}{sub 3},{eta}{sup 2}-SO{sub 2})] (1) and [PPN]{sub 2}[Fe{sub 3}(CO){sub 8}({mu}-SO{sub 2}){mu}{sub 3}-S] (2), which were characterized by infrared spectroscopy, {sup 13}C NMR, and X-ray crystallography. Further reaction of 1 with sulfur dioxide results in the formation of 2 in 48% yield. Reaction of SO{sub 2} with [PPN]{sub 2}[Fe{sub 4}(CO){sub 13}] yields [PPN]{sub 2}[Fe{sub 2}(CO){sub 6}({mu}-SO{sub 2}){sub 2}] (3) which was characterized by infrared spectroscopy, {sup 13}C NMR, mass spectrometry, and X-ray crystallography. One equivalent of sulfur dioxide with [PPN]{sub 2}[MFe{sub 3}(CO){sub 14}C] (M = Cr, W) produces [PPN]{sub 2}[Fe{sub 3}(CO){sub 8}({mu}-SO{sub 2})-({mu}{sub 3}-CCO)] (4), which on further reaction with SO{sub 2} gives the known cluster [PPN]{sub 2}[Fe{sub 3}(CO){sub 7}({mu}-SO{sub 2}){sub 2}({mu}{sub 3}-CCO)] (5). An excess of sulfur dioxide with [MFe{sub 3}(CO){sub n}C]{sup x{minus}} (M = Cr, W: n = 13, x = 2; M = Rh: n = 12, x = 1; M = Mn: n = 13, x = 1) produced 5 as the only identified product.
