In the title compound, 2C(6)H(9)N(2) (+)·C(5)H(2)N(2)O(4) (2-)·3H(2)O, the 1H-pyrazole-3,5-dicarboxyl-ate anion is close to planar [maximum deviation = 0.208 (1) Å]. The two distinct 2-amino-5-methyl-pyridinium cations are also almost planar, with maximum deviations of 0.018 (2) and 0.014 (2) Å. In the crystal, pairs of inter-molecular N-H⋯O and O-H⋯O hydrogen bonds connect neighbouring mol-ecu...
In the title mononuclear complex, [Ni(C(3)H(2)O(4))(C(15)H(10)N(4))(H(2)O)]·3H(2)O, the metal center is coordinated in a distorted NiN(3)O(3) geometry. In the crystal structure, inter-molecular O-H⋯O hydrogen bonds link the components into a two-dimensional network. In addition, there are weak π-π stacking inter-actions between symmetry-related phenanthroline rings, with a centroid-centroid dis...
The Ni(II) atom in the title compound, [Ni(C(8)H(5)NO(4))(C(12)H(8)N(2))(H(2)O)(3)]·3H(2)O, is six-coordinated in an NiN(3)O(3) octa-hedral geometry. The triply water-coordinated Ni(II) atom is chelated by the phenantroline ligand and is additionally coordinated by the amino group of the 5-amino-isophtalate anion. The anion, the coordinated and the uncoordinated water mol-ecules inter-act throu...
In the title compound, [Cu(2)(C(12)H(8)N(3)O(2))(2)(C(6)H(8)O(4))(H(2)O)(2)]·3H(2)O, both crystallographically independent Cu atoms are in similar distorted square-pyramidal coordination environments. The dinuclear complex mol-ecules are assembled into one-dimensional supra-molecular chains extending in the [100] direction by hydrogen bonds. Inter-chain hydrogen bonds further link these chains ...
In the title compound, C11H11N3O3S·3H2O, the non-H atoms of the main mol-ecule are approximately planar, with an r.m.s. deviation of 0.030 Å. There is a bifurcated intra-molecular N-H⋯(O,S) hydrogen bond present forming S(6) and S(5) ring motifs. In the crystal, O-H⋯O and N-H⋯O hydrogen bonds link the molecules into a three-dimensional network.
In the cerate(IV) anion of the title salt, (C(2)H(10)N(2))(5)[Ce(2)(SO(4))(9)]·3H(2)O, the two metal atoms are bridged by three sulfate units; each metal atom is itself chelated by other three sulfate units so that the metal atoms exist in nine-coordinate tricapped trigonal-prismatic geometries. The anions, cations and uncoordinated water mol-ecules are linked by O-H⋯O and N-H⋯O hydrogen bonds,...
BACKGROUND Gonorrhoea has been among the easiest infections to cure with antibiotics. Nevertheless, emerging resistance has driven repeated treatment shifts. Decreased cephalosporin susceptibility is now being reported. We examined cephalosporin MIC trends for Neisseria gonorrhoeae in the UK and undertook pharmacodynamic analyses to predict efficacy against strains with raised MICs. METHODS N...
BACKGROUND Surveillance of Neisseria gonorrhoeae antimicrobial susceptibility in Europe is performed through the European Gonococcal Antimicrobial Surveillance Programme (Euro-GASP), which additionally provides data to inform the European gonorrhoea treatment guideline; currently recommending ceftriaxone 500 mg plus azithromycin 2 g as first-line therapy. We present antimicrobial susceptibility...
