Dear all, I have a bibliographic problem and I will be very grateful if someone of you could help me to solve it. The structure of ethilaminobis(methylene phosphonic acid), of formula (H2O3P-CH2)2-N-CH2-CH3 has been published in Zh. Strukt. Khim. (1985), 26(5), 131. I cannot find out the article, furthermore it is written in russian! Do you know any other source for this structure? Alternatively, can you send me the essential structural data? Thank you very much. Riccardo Vivani
