| Abstract: | In the ethanol solution,the oil-soluable tea-polyphenols and As3+ in molar ratio 2∶1,4∶1,6∶1 respectively reacted at pH=4.0 and 40～45 ℃ for 15 hour to give the title complexes through phase transfer method.The yield is 59%.They were characterized by UV absorption spectra as 267.50,218.00,220.50 nm;by FTIR as 3 415.6,2 918.6,2 850.2,1 708.2,1 457.3,1 370.4,1 224.2,1 144.0,760.5 cm-1;EX spectrum λmax was 257.0,591.1,593.7,590.3,591.0,591.5 nm;and by XRD λ as 3.697 4,4.186 0,12.076 2,15.474 7 nm.1HNMR δ=0.782,1.193,1.483～1.586,1.957～2.170,2.479,3.116,3.970～3.981,5.231～5.953,6.537～7.30.The final coordination was two complexes polycrystalline compounds. |
