Abstract
In an attempt to characterise definitively the species previously reported to be [Fe(NCMe)2(dppm)]I2, the structure of [Fe(NCMe)2(dppm)2][FeI4]·2H2O (dppm = Ph2PCH2PPh2) has been determined. Thus dppm is capable of forming bis(bidentate) complexes with iron(II). However, such materials are air-sensitive, and in attempting to reproduce the synthesis of the dihydrate the novel diphosphine dioxide complex [Fe(dppom)3][I3]2[dppom = Ph2P(O)CH2P(O)Ph2] was actually isolated and characterised by X-ray structure analysis. It is doubtful whether [Fe(NCMe)2(dppm)]I2 has ever been prepared.Keywords
