Summary
-
1.
It has been found that mercuric halides react with full esters of phosphorous acid with formation of complex compounds. The following compounds have been isolated in the crystalline form: [HgBr2 · P(OCH3)3]2; [HgCl2 · P(OC2H5)3]2. [HgBr2 · P(OC2H5)3]2; [HgCl2 · P(OC3H7-i)3]2. [HgBr2 · P(OC3H7-i)3]2; [HgI2 · P(OC3H7-i)3]2.
-
2.
Molecular weight determinations by cryoscopy in benzene on the compounds formed showed that their molecules are dimeric.
-
3.
The complex compounds obtained, complexes of mercuric halides with trialkyl phosphites [(RO)3P · HgX2]2, are analogs of the corresponding phosphine complexes [R3P · HgX2]2, and they belong to the bridged type.
