Schiff base derivatives of titanium(IV) and zirconium(IV)

Abstract

The reactions of a few bifunctional and tridentate Schiff bases with titanium‐(IV) and zirconium(IV) isopropoxides in equimolar and bimolar ratios are described. The resulting compounds have been obtained in almost quantitative yields and are of the general formulae M(SB)x(OPri)4−2X (where M = Ti or Zr; SB‐ = anion of the Schiff base SBH2 and x = 1 or 2). Their molecular weights have been determined ebullioscopically and IR spectra recorded.

“…Nediurn to strong intensity bands in the region, 620-580 em-' may be assigned to v(M-0) vibrations in view of the previous assignments [4]. A band of medium intensity in the region, j30 & 10 om-l in these derivatives may be attributed to v(3I-N) [lo].…”
