A novel route to synthesize some titanium(IV) complexes containing acetylacetone, straight chain carboxylic acid and hydroxycarboxylic acid ligands has been investigated. Complexes with the general formula [Ti(acac)Cl(2-n)(OOCR*)(n)(OOCC(15)H(31))] (where Hacac=acetylacetone, R*COOH=hydroxycarboxylic acids and n=1 or 2) have been isolated and characterized. Molecular weight determinations indicated
研究了合成一些含有乙酰丙酮,直链羧酸和羟基羧酸配体的钛(IV)配合物的新途径。具有通式[Ti(acac)Cl(2-n)(OOCR *)(n)(OOCC(15)H(31))]的配合物(其中Hacac =乙酰丙酮,R * COOH =羟基羧酸和n = 1或2)已被分离并鉴定。分子量的测定表明了复合物的单核性质。在电子光谱中观察到LMCT带。红外光谱暗示了配体的双齿性质。根据荧光光谱观察到配合物的荧光行为。粉末XRD表明它们是半结晶,其微晶尺寸在136-185nm范围内。透射电子显微镜(TEM)显示直径约200 nm的球形颗粒。
