Hexaaquagallium(III) trinitrate trihydrate

Hexaaqua­gallium(III) trinitrate trihydrate

The title compound, [Ga(H(2)O)(6)](NO(3))(3)·3H(2)O, is isostructural to other known M(III) nitrate hydrates (M = Al, Cr, Fe). The structure contains two distinct octa-hedral Ga(OH(2))(6) units (each of symmetry) which are involved in inter-molecular hydrogen bonding with the three nitrate anions and three water mol-ecules within the asymmetric unit.

Glycerol trinitrate

1,1,4,7,7-Penta­methyl­diethylenetri­ammonium trinitrate

In the title compound, C9H26N3 (3+)·3NO3 (-), the triprotonated 1,1,4,7,7-penta-methyl-diethylenetri-amine mol-ecules are linked to the nitrate anions by multiple bifurcated N-H⋯(O,O) and weak C-H⋯O hydrogen bonds. The organic cation is characterized by N-C-C-N torsion angles of -176.2 (2) and 176.6 (2)°.

Comparison with glyceryl trinitrate

The coronary haemodynamic effects of nifedipine and glyceryl trinitrate were compared in 22 patients undergoing investigations for suspected coronary artery disease. Myocardial blood flow was estimated by the coronary sinus thermodilution technique. In sinus rhythm nifedipine increased mean coronary sinus flow from 135 ml/min to 152 m/min, and reduced arterio-coronary sinus oxygen difference fr...

Benzimidazolium 3,5-dicarb­oxy­benzoate trihydrate

Cocrystallization of benzimidazole with benzene 1,3,5-tricarb-oxy-lic acid in slightly basic medium afforded the title compound, C(7)H(7)N(2) (+)·C(9)H(5)O(6) (-)·3H(2)O, in which one of the imidazole N atom is protonated and one carb-oxy-lic group of aromatic acid is deprotonated. In the crystal structure, inter-molecular N-H⋯O hydrogen-bonding connects the two organic components into dimers, ...
