Abstract

The reactions of bromomalonaldehyde anion (BMA) with several metal(II) chlorides have been studied and the syntheses of the tris(chelate) AsPh4[Fe(BMA)3] complex and the complexes [M(BMA)2(H2O)2] and [M(BMA)2] (M  FeII, CoII, NiII, CuII) are reported. Complexes CoBr2(CNR)4, [FeBr(CNR)5]BPh4 and [Cu(CNR)4]Br (R  4-CH3C6H4) were obtained by reaction of the BMA derivatives with RNC.
