Abstract
The complexes Fe(CO)3L2, (L = Ph3P, Ph3As, Ph3Sb), react with mercuric halides to form 1 : 1 adducts; spectroscopic and conductivity evidence suggests their formulation as metal–donor complexes L2(CO)3Fe → HgX2. A 1 : 2 complex is formed by Fe(CO)3{(PhO)3P}2 and consists of a 1 : 1 compound plus a molecule of mercuric halide. Analogous structures are suggested for Fe(CO)5,nHgX2, (n= 1, 2).Features of the low-frequency spectra of the parent compounds and the adducts are discussed. Mercury–halogen frequencies are correlated with various structural situations.
