Selective formation of alkoxo-bridged titanium(IV) polynuclear complexes with polyaminopolycarboxylate: First titanium(IV) octanuclear complex containing cubic-type {Ti-4(mu-oxo)(4)}(2)(mu-alkoxo)(4) core
Two kinds of alkoxo-bridged Ti(IV) polynuclear complexes were selectively obtained depending on reaction conditions. Crystal structures of the dinuclear complex [Ti-2(mu-dptaO)(2)](2-) and the novel octanuclear complex [{Ti-4(mu-O)(4)}(2)(mu-dptaO)(4)](4-) (H(4)dptaOH = 2-hydroxypropane-1,3-diamine-N,N, M,AP-tetraacetic acid) were determined. The obtained complexes were spectrochemically characterized.
