Compound [Ni(hmt)2(SCN)2(H2O)2][Ni(SCN)2(H2O)4](H2O)2 (hmt=hexamethylenetetramine) was pre-pared and structurally characterized by means of X-ray single crystal diffraction. The two neutral units [Ni(hmt)2(SCN)2(H2O)2] and [Ni(SCN)2(H2O)4] are joined together through hydrogen bonds N…H-O, O…H-O and S…H-O. In the solid state, the compound has three-dimensional network structure. The determination of its variable-temperature magnetic susceptibilities (5~300K) shows that the magnetic behavior obeys the Curie-Weiss law over the whole temperature ranges.  相似文献

A new photoluminescence supramolecular compound [Cu(HIm)(PPh3)2I] was synthesized and characterized by single crystal X-ray diffraction, elemental analysis, as well as IR, UV-Vis absorption and luminescence spectrometry. It crystallizes in monoclinic system, space group P21/n with a=1.3335(14) nm, b=1.310 3(9) nm, c=2.154 4(16) nm, α=90.00°, β=101.130(10)°, γ=90.00°, V=3.694(5) nm3, Z=4, Dc=1.408 Mg·m-3. The single crystal structure indicates that the 2D supramolecular network structure is established by intermolecular weak N-H…I and C-H…I hydrogen-bonding interactions. The N-H…I is responsible for the conformation of one-dimensional zigzag chains and the C-H…I connects these chains to form two-dimensional supramolecular hydrogen-bonding network. At room temperature in the solid state, the complex is photoluminescent with an emission peak maximum at 460 nm, upon excitation at 330 nm. The emission is assigned to the metal-perturbed intraligand (PPh3) in nature. CCDC: 228743.  相似文献

The crystal is of triclinic, space group P with a = 9.21(3), b = 10.17(3), c = 10.77(3) (A), α = 77.017(16), β = 89.80(8), γ = 68.46(7)°, V = 911(5) (A)3, Z = 2, (D/s)max = 0.001, Mr = 473.94, Dc = 1.728 g/cm3, μ(MoKα) = 1.365 mm-1, F(000) = 486, the final R = 0.0246 and wR = 0.0628 for 3809 observed reflections with I > 2σ(I).

[Zn(o-bda)(phen)(H2O)]n·nH2O (C22H20N2O6Zn) (1) [where o-bda is o-phenylenediacetic acid dianion and phen is 1,10-phenanthroline] crystallizes in triclinic system, space group P1 with a=0.826 5(4) nm, b=1.042 4(5) nm, c=1.238 1(6) nm, α=76.987(9)°, β=70.987(9)°, γ=78.281(8)°, V=0.9728(8) nm3, Z=2, Dc=1.617 g·cm-3, μ=1.308 mm-1 and F(000)=488. Zn(Ⅱ) ion has a distorted trigonal bipyramid coordination geometry formed by two carboxyl O atoms from two different o-bda groups, two N atoms from the phen ligand and one terminal water molecule. Adjacent Zn(Ⅱ) ions are interlinked by o-bda groups into a infinite zigzag chain structure with a Zn…Zn distance of 0.825 6(4) nm. The adjacent zigzag chains may also be paired under direction of supramolecular recognition and attraction through both π-π stacking and hydrogen bonding interactions into molecular zippers, which further interlinked into a three-dimensional supramolecular network by these noncovalent interactions.

In the title compound, the nickel ion is coordinated by a nitrogen atom and an oxygen atom from the orotate ligand, two nitrogen atoms from 2, 2'-bipy and two oxygen atoms from the coordinated water molecules in a distorted octahedral geometry. The presence of intermolecular hydrogen bonding and (-( stacking interaction of aromatic rings from 2, 2'-bipy results in a 3D structure.  相似文献
