single-crystal X-ray diffraction. Reactions of H5L with samarium(III) chloride and calcium(II) chloride resulted in three new compounds, Sm[(O3PCH2)2NH-CH2C6H4-COOH]·H2O (1), Ca[H(O3PCH2)2NH-CH2C6H4-COOH]·H2O (2), and Ca[(HO3PCH2)2NH-CH2C6H4-COOH]2·4H2O (3). The single-crystal structure determination of the title compounds reveals that in H5L as well as in compounds 1, 2, and 3 zwitterions are present
