1. The vibrational spectra of the 2-chloro and 2-alkoxy derivatives of 1,3,2-dioxastibinane in various phase states indicate they are capable of self-association through Sb-O...Sh and Sb-Cl...Sb bridges of various types, determined by the steric stra

1. It has been shown for the first time by means of1H NMR that in solutions of cyclic compounds of trivalent antimony, dimeric structures with the participation, of endocyclic and exocyclic O atoms are realized. The molecular dynamics are determined

1. We have synthesized 1,6,10-trioxa-8,8-dimethyl[(5-methoxy)-5-phosphaspiro(4.5)]dec-2-ene, a compound in which the trigonal-bipyramidal phosphorus bond arrangment undergoes pseudorotation at temperatures below 36°C. Thermodynamic activation parame

1. The action of an excess of chlorine on the corresponding alkoxy- and chloroalkoxy derivatives of Sb(III) produced trichlorodimethoxy-, dichlorotrimethoxy-, and trichlorodiethoxyantimony, which have not been described in the literature, as well as

The structure of dimers [Cl5–n Sb(OCH3) n ]2 with n = 1–5 and their polyhedral stereoisomery have been studied on the basis of 1H nmr data. It has been shown that in the case of n = 1 only one nondegenerate dimeric structure and with n = 5 only a

1. Chlorotetramethoxyantimony was obtained by the action of acetyl chloride on pentamethoxyantimony. 2. Triethoxy-, tripropoxy-, and triisobutoxyantimony are partially associated under conditions of cryoscopy in cyclohexane, while triisopropoxy- and

1. A mechanism has been proposed for intramolecular and intermolecular ligand exchange in a series of pentacoordinated derivatives of Sb. 2. An interpretation has been given for the temperature dependence of the NMR spectra within the framework of co
