A new mononuclear gadolinium complex [Gd(NO3)·L](NO3)2 of Schiff base cryptand was obtained by condensation of tris (2-aminoethyl)amine with 2,6-diformyl phenol in template procedure. The complex was characterized by elemental analysis, IR, and x-ray single crystal diffraction analysis. Gadolinium is nine-coordinate in trigonal tricapped prism with five oxygen atoms from three phenols and a bidentate nitrate group, and four nitrogen atoms from three imino C=N bonds and a tertiary amine in the cryptand.

A new copper(H) complex [Cu2(DMF)(H2O)(C7H4NO4)2(C7H3NO4)]2-3.5DMF has been synthesized and its structure was determined by single-crystal X-ray diffraction. The crystal is of triclinic, space group P1^- with a = 10.722(3), b = 18.170(4), c = 20.923(7)A,α = 105.297(9), β = 101.701(10), γ = 105.74(1)°, V= 3615(1)A^3, Z = 2, C58.50H64.50Cu4N1l.50O3150, Mr = 1686.90, Dc = 1.550 g/cm^3,μ= 1.255 mm^-1, F(000) = 1728.00, T = 150(2) K, the final R = 0.0640 and wR = 0.173 for 11310 observed reflections with I 〉 2σ(I). In the crystal, each formular unit consists of two dinuclear copper(H) compounds, between which the O-H…O hydrogen bonds exist. Each Cu^Ⅱ cation is six-coordinated in an octahedral geometry. The intermolecular hydrogenbonding interaction leads to a 3-D framework of the title compound.  相似文献
