Early diagnosis of diabetic peripheral neuropathy is important for the successful treatment of diabetes mellitus. In the present study, we recruited 500 diabetic patients from the Fourth Affiliated Hospital of Kunming Medical University in China from June 2008 to September 2013: 221 cases showed symptoms of peripheral neuropathy (symptomatic group) and 279… (More)
A number of linear coordination polymers have been assembled from lanthanide cations (Ln 3+) and cucurbituril (Q) in the presence of [CuCl 4 ] 2− or [CoCl 4 ] 2− anions acting as inorganic structure inducers in HCl solution. X-ray diffraction analysis has revealed that they form three groups of isomorphous structures. Generally, the complexes of Q… (More)
The asymmetric unit of the title compound, (C(24)H(26)N(2))[ZnCl(4)], consists of two 2,2'-(hexane-1,6-di-yl)diisoquinolinium cations and two [ZnCl(4)](2-) complex anions. The [ZnCl(4)](2-) anions have a distorted tetra-hedral geometry. The dihedral angles between the isoquinoline rings of the two cations are nearly equal [16.1 (2) and 16.3 (2)°]. In the… (More)
In the crystal of the title compound, [Ni(NO(3))(2)(C(18)H(10)N(4))(H(2)O)]·H(2)O, the Ni(II) ion is coordinated in a distorted octahedral geometry by two N atoms of the 1,10-phenanthroline moiety of the ligand, three O atoms from two nitrate anions and an O atom from one water mol-ecule. O-H⋯O hydrogen bonds between the coordinated and the solvent water… (More)
The organic cation of the title salt, C(17)H(12)N(4)O(2+)·2Cl(-)·H(2)O, is nearly planar, the dihedral angle between two pyridine rings being 2.53 (16)° and that between the pyridinum and furan rings being 4.17 (19)°. Mol-ecules are linked via N-H⋯O, N-H⋯Cl and O-H⋯Cl hydrogen bonds, forming a three-dimensional framework and π-π stacking inter-actions help… (More)
In the title compound, C(12)H(11)N(3)O(3)S·H(2)O, the pyridine ring makes a dihedral angle of 24.78 (14)° with the phenyl ring. Intra-molecular N-H⋯O and inter-molecular O-H⋯O hydrogen bonds are observed and stabilize the packing in the crystal structure.
In the title compound, C(21)H(26)N(4) (2+)·Cl(-)·NO(3) (-)·H(2)O, the organic cations, anions and water mol-ecules are linked through N-H⋯Cl, N-H⋯O, N-H⋯N and O-H⋯Cl hydrogen bonds, forming a three-dimensional framework, assisted by C-H⋯π inter-actions.
In the crystal structure of the title compound, C(6)H(8)N(2)O·CH(4)N(2)O·H(2)O, mol-ecules are linked via N-H⋯O, O-H⋯N and O-H⋯O hydrogen bonds, forming a three-dimensional framework.
In the crystal structure of the title compound, C(13)H(11)N(4)O(3) (+)·Cl(-), the dihedral angle between the two pyridine rings is 9.72 (9) Å. Ions are linked via N-H⋯Cl, O-H⋯Cl and O-H⋯O hydrogen bonds, forming a three-dimensional framework.
In the title compound, C 10 H 12 N 8 O 4 ÁH 2 O, prepared from the reaction of glycoluril with paraformaldehyde, the organic molecule has mm symmetry. The asymmetric unit comprises one quarter of the molecule and a half-molecule of water. The dimer is formed by bridging two glycoluril molecules with methylene groups at the 1 and 6 positions. In the crystal… (More)
