中文摘要	Two new Cr(III) complexes, [Cr(bpb)(H2O)(OH)]center dot 3H(2)O (1) and [Cr(bpb)(H2O)(N-3)]center dot H2O (2) have been synthesized and structurally characterized. Both complexes were unexpectedly obtained as single crystals during the reactions of [Cr(bpb)(CN)(2)](-) or [Cr(bpb)(N-3)(2)](-) with [Ni(L)](ClO4)(2) (L = 3,10-dimethyl-1,3,6,8,10,12-hexaazacyclotetradecane) or MX2 center dot nH(2)O (M = Cu, Ni and Mn, X = Cl- and ClO4-). Complex I crystallizes in the triclinic system, space group P-1, formula CrC18H21N4O7 with a = 7.1543(17) angstrom, b = 12.420(3) angstrom, c = 12.955(3) angstrom, alpha = 115.021(5)degrees, beta = 95.544(5)degrees, and gamma= 101.575(5)degrees. Complex 2 crystallizes in the monoclinic system, space group P2(1)/c, formula CrC18H16N7O4 with a = 11.7171(9) angstrom, b = 9.4999(7) angstrom, c = 16.8799(13) angstrom, and, beta = 97.449(2)degrees. Both complexes exhibit distorted octahedral coordination environment with four nitrogen atoms of bpb(2-) situated at the equatorial plane (Cr-N bond distances range from 1.961(3) to 2.1088(15) angstrom), and the remaining two trans-positions occupied by terminal ligands H2O/HO and H2O/N-3 in 1 and 2, respectively. It is noteworthy that a hydrogen-bonded folded ladder-like structure involving twelve O atoms in 1 and a chair-like hexagonal hydrogen-bonded cluster containing six O atoms are formed.
