The synthesis and crystal structure of Cu(II) complex of a binucleating tridentate ligand 1,3-bis [N, N-bis(2-picolyl) amino] propan-2-ol (I) is being reported. The two chelating bispicolylamine arms in I are tethered by a 2-hydroxypropyl group with Cu( II) coordinating in a slightly distorted square planar geometry to give [Cu-2( I)(OH2)(Cl)](ClO4)(3) center dot 2H(2)O (II). The crystal data for II: Triclinic, space group P (1) over bar with cell dimensions of a = 13.345 (4) angstrom, b = 13.873 ( 4) angstrom, c = 12.867 (2) angstrom, alpha = 111.68 (2)degrees, beta = 100.34 (2)degrees, gamma = 65.83 ( 2)degrees, V = 2018.4 ( 9) angstrom(3), F. W. = 962.46, rho(calc) = 1.583 g cm(-3) for Z = 2,mu = 13.93 cm(-1).
