Monohydrate monohydrochloride of bis(dialkylaminomethyl)phosphinic acids of the composition, [(R1HCH2)2PO2]Cl_H2O {R1 = Me2 N, Et2N, (n-Bu)2N, C5H10N, OC4H8N}, dihydrate dihydrochloride of bis(dialkylaminomethyl)phosphinic acids, [(R2HCH2)2P(O)OH]Cl2_2H2O {R2 = Me2 N, C4H8N, C5H10N, OC4H8N}, and their copper(II) and cobalt(II) addition compounds with tetrahedral [MCl4]2- ions {M = CuII, CoII} have been prepared and characterized by elemental analyses, effective magnetic moments, IR, VIS, and 1H and 31P-NMR spectra. Crystal and molecular structures of [(OC4H8NHCH2)2PO2]Cl_H2O and [(OC4H8NHCH2)2PO2]2CuCl4 have also been determined.
