Synthesis, IR spectra, and structure of chelate compounds of oxotungsten(6) with o-hydroxoyazomethines; crystal structures of the complexes oxotrichloro(salicylal-4-R-phyenyliminato)tungsten(6) (R = Me, Br, and OMe)

Synthesis and IR-spectroscopic investigation have been carried out for seven [WOCl3(L)] compounds with different 4-R-substitutes (Me(1), Br(2), OMe(3), OH(4), H(5), COOEt(6), NO2(7) and [WOCl(OMe)2(L)] complex) (R Br(8)). On the basis of IR-spectroscopic data on assumption about mer-octahedral structure of 1-8 compounds is made, it is confirmed by the results of X-ray structural analysis of 1-3 compounds. 31 refs.; 1 fig.; 5 tabs
