The title complex, [Fe(C(15)H(10)ClN(3))(2)](NO(3))(2)·2H(2)O, has a six-coordinate iron(II) center balanced by two nitrate anions. The Fe atom lies on a twofold rotation axis. The complex exhibits an octa-hedral coordination configuration, where the dihedral angle between the two planar tridentate ligands is 92.4 (1)°. The crystal structure involves O-H⋯O hydrogen bonds.

The water-coordinated Zn(II) atom in the title salt, [Zn(C(5)H(5)N(3)O(2))(2)(H(2)O)(2)](NO(3))(2), is N,O-chelated by a zwitterionic amino-pyraziniocarboxyl-ate unit; the metal atom, which lies on a center of inversion, shows an octa-hedral coordination. The nitrate ion inter-acts indirectly, through N-H⋯O hydrogen bonds. In the crystal, adjacent cations and anions are connected by O-H⋯O hydro...

In the title molecular salt, C(7)H(20)N(2) (2+)·2NO(3) (-), the crystal structure exhibits an unusual back-to-back paired double-stacked packing arrangement culminating in an overall double zigzag pattern of the dications. The nitrate anions form a ring around one pair of double-stacked dications. An intricate three-dimensional N-H⋯O and N-H⋯(O,O) hydrogen-bonding network exists in the crystal ...

background: the most favorable method for cervical ripening is not fully agreed upon by practitioners; however, vaginal administration of isosorbide mononitrate (imn) is considered a low‑risk method of labor induction for pregnant women at full term. our study was designed to assess the effect of imn on cervical ripening and labor induction among primiparous women in iran. materials and methods...

In the title compound, Pb(2)(HPO(3))(NO(3))(2), the two distinct Pb(2+) ions (both with site symmetry m) adopt irregular PbO(10) coordination polyhedra. The structure is completed by two distinct nitrate groups (in which one O atom and the N atom have m site symmetry for both ions) and an HPO(3) (2-) anion (in which one O atom and the P and H atoms have m site symmetry). The connectivity of the...

The asymmetric unit of the title compound, [Ni(C(3)H(8)N(2)O(2))(3)](NO(3))(2), contains two independent cations, each built up around a fac-NiN(3)O(3) octa-hedron, and four nitrate anions. Numerous cation-to-anion N-H⋯O hydrogen bonds, some of which are bifurcated, help to establish the packing.

In the title compound, C(11)H(15)N(3) (2+)·2NO(3) (-), one of the imidazole N atoms and the N atom of the pyrrolidine ring are protonated. The pyrrolidine ring adopts an envelope conformation, with the C atom carrying the benzoimidazolium substituent as the flap atom. In the crystal structure, cations and anions are linked through N-H⋯O hydrogen bonds, forming chains that run parallel to the c ...

In the centrosymmetric title compound, [Co(C6H12N4O3)2](NO3)2·4H2O, the Co(II) ion, lying on an inversion center, is O,N,O'-chelated by two nitrilo-triacetamide mol-ecules, forming a distorted octa-hedral geometry. In the crystal, extensive O-H⋯O and N-H⋯O hydrogen bonds link the complex cations, nitrate anions and lattice water mol-ecules into a three-dimensional network.

The crystal structure of the title compound, C(10)H(26)N(2) (2+)·2NO(3) (-), exhibits a back-to-back paired double-stacked packing arrangement culminating in an overall double zigzag pattern of the dications. Each pair of double-stacked dications is surrounded by a ring of ten nitrate anions. An intricate three-dimensional N---H...O and N---H...(O,O) hydrogen-bonding network exists in the cryst...

A 13 year old boy is described with hypereosinophilia associated with Kimura's disease, who showed repeated life threatening syncopal attacks during daily activities or at rest. Coronary arteriography demonstrated small aneurysms with irregular vessel walls of both coronary arteries, and the absence of organic stenotic lesions. Infusion of a minimal dose of ergonovine into the right coronary ar...
