The project deals with crystal structures and character of bonding in compounds cosntaining elements of the V., VI., and VII. group. The research will concentrate on the following classes of compounds: (a) structure of betaines of substituted (oligo) pho sphoric acids of the type B.P.X2Y, where B is a Lewis base, X=O,S, and Y=F,Cl, (b) structure of cyclodiphosphathianes and thiazadiphosphetidines, (c) structure of products of the reaction of amidophosphazenes with halogenides and oxohalogenides of sulfur and selenium, (d) structure od cyclic and linear P,N,S compounds, (e) structure of DA-complexes of selenium oxides, (f) structures solved in collaboration with other institutions. The metodics and experimental techniques developped during the previous p roject 203/95/1190, low temperature diffractometry and charge density calculations, will be used.
