ML3(H2O)2(ClO4)3 (M = Pr, Nd, Er; HL = L-proline) and Pr2L6(H2O)4(ClO4)6 (I) were prepared from the metal perchlorates and the amino acid. Crystal data: I; monoclinic, space group P21, a 0.9879(3), b 2.1883(4), c 1.3393(2) nm, b 91.23(2)? Z = 2, R = 0.035. IR and thermal decomposition data are given for the complexes. L is bridging in I and H2O is coordinated.

Key words: INFRARED SPECTROPHOTOMETRY, ELEMENTAL ANALYSIS, CRYSTAL STRUCTURE, PROLINE, RARE EARTH METAL COMPLEX, PERCHLORATE, PRASEODYMIUM COMPLEX, NEODYMIUM COMPLEX, FOUR-CIRCLE DIFFRACTOMETER, ERBIUM COMPLEX
