measurements, infrared and proton magnetic resonance spectral studies. Solution studies reflect the non-ionic nature of these compounds. Infra-red spectral studies predict the unidentate nature of salicylate, benzoate and cinnamate and bidentate nature of oxalate, o-phthalate and succinate groups. A PMR spectral study confirms their proposed stoichiometry. These compounds possess a trigonal bipyramidal structure
摘要 通过双(对甲氧基苯基)碲氧化物和双(对羟基苯基)碲氧化物反应合成一些新的二芳基碲(IV)二羧酸盐(水杨酸盐、苯甲酸盐、肉桂酸盐)和羧酸盐(草酸盐、邻苯二甲酸盐、琥珀酸盐)。报告了相应的羧酸。所得羧酸盐已进行元素分析、电导和低温测量、红外和质子磁共振光谱研究。溶液研究反映了这些化合物的非离子性质。红外光谱研究预测了水杨酸酯、苯甲酸酯和肉桂酸酯的单齿性质以及草酸酯、邻苯二甲酸酯和琥珀酸酯基团的双齿性质。PMR 光谱研究证实了他们提出的化学计量。这些化合物具有带有四配位中心碲原子的三角双锥体结构。
