Abstract	A new heterobimetallic nitrilotriacetatoperoxotitanate complex of titanium and lead [Pb(H$_{2}$O)$_{3}$]$_{2}$[Ti$_{2}$(O$_{2}$)$_{2}$O(nta)$_{2}$]·4H$_{2}$O (C$_{6}$H$_{6}$O$_{6}$N=H$_{3}$nta) was isolated in pure crystals directly from the solution containing tetrabutyl orthotitanate, hydrogen peroxoide, lead acetate, and nitrilotriacetic acid at pH = 2.0–4.0. The isolated complex was characterized by elemental analyses, IR spectrum, thermal analysis (TG), and single-crystal X-ray diffraction. The single-crystal X-ray structural analysis revealed that the titanium atom is N,O,O′,O′′-chelated by the nitrilotriacetate and O,O′-chelated by the peroxo group and was coordinated to the bridging O atom in an overall pentagonal-bipyramidal geometry. The thermal decomposition of this precursor led to the formation of phase-pure lead titanate (PbTiO$_{3}$) at ≥450 °C. The morphology, microstructure, and crystalline of the resulting PbTiO$_{3}$ product have been characterized by BET, transmission electron microscopy, and powder X-ray diffraction. The TEM micrographs revealed that the size of the as-synthesized crystallines to be 50–100 nm range. The BET measurement revealed that the PbTiO$_{3}$ powders had a surface area of 5.6 m$^{2}$/g.
