In the title compound, [Mg(SO(4))(C(12)H(8)N(2))(H(2)O)(3)], the Mg(II) centre exhibits a slightly distorted octa-hedral coordination environment defined by two N atoms from a 1,10-phenanthroline mol-ecule, one O atom from a sulfate dianion and three meridionally arranged O atoms from coordinated water mol-ecules. The crystal structure involves intra- and intermolecular O-H⋯O hydrogen bonds.

In the title compound, C(12)H(15)ClNO(+)·C(4)H(5)O(6) (-), the cyclo-hexa-none ring adopts a chair conformation. The benzene ring is significantly twisted so that it is in an almost perpendicular position to the C-N bond with a C(Ar)-C(Ar)-C-N torsion angle of -96.5 (5)°. Intermolecular N-H⋯O and O-H⋯O hydrogen bonds are observed in the crystal structure.

The compounds 6-(pyrrol-2-yl)-2,2'-bipyridine, 2-(pyrrol-2-yl)-1,10-phenanthroline and 2-(2-(N-methylbenz[d,e]imidazole)-6-(pyrrol-2-yl)-pyridine were synthesized by using an in situ generated boronic acid for the Suzuki coupling. Crystals of the products could be grown and exhibited interesting structures by X-ray analysis, one of them showing a chain-like network with the adjacent molecules l...

In the title compound, C(19)H(13)N(3)O, the dihedral angle between the two quinoline systems is 11.54 (3)°. The mol-ecular conformation is stabilized by intra-molecular N-H⋯N and C-H⋯O hydrogen bonds, with N-H⋯N being bifurcated towards the two N atoms of the two quinoline rings. In the crystal, there are weak intermolecular π-π inter-actions present involving the quinoline rings [centroid-cent...

# 2006 International Union of Crystallography All rights reserved In the crystal structure of the title compound, C16H18N2O2, the indole moiety is nearly planar. The two carbonyl groups are almost perpendicular, with a torsion angle of 105.7 (4) , and the single C—C bond linking the two carbonyl groups is 1.515 (5) Å in length. The molecules are linked together by N—H O intermolecular hydrogen ...

A series of 15 glycoside-derived tricarbonyl(η(6)-arene)chromium complexes were prepared in 19-87% yield by heating fully acetylated or methylated aryl O-, S-, N- and C-glycosides of D-glucopyranose and D-mannopyranose with hexacarbonylchromium. All tricarbonylchromium complexes were fully characterized. The structures of nine crystalline complexes were determined by X-ray diffraction, revealin...

The solid state structure of 1-((1H-benzotriazol-1-yl)methyl)naphthalen-2-ol, C17H13N3O, shows that this Mannich base crystallizes forming intermolecular N...HO hydrogen bonds, rather than intramolecular ones. Factors contributing to this choice of hydrogen-bonding mode are discussed. The compound crystallizes in the monoclinic system, P2(1)/c space group, with lattice constants: a = 11.7934(9)...

The asymmetric unit of the title compound, C(12)H(13)NO(3), contains two independent mol-ecules. The conformation of the N-H bond and the C=O bond in the amide segment are anti to each other. The mol-ecular conformation of each mol-ecule is stabilized by an intra-molecular O-H⋯O hydrogen bond. In the crystal, mol-ecules are connected through intermolecular N-H⋯O hydrogen bonds. In addition, the...

We reported an automated dielectrophoretic (DEP) tweezers-based force spectroscopy system to examine intermolecular weak binding interactions, which consists of three components: (1) interdigitated electrodes and micro-sized polystyrene particles used as DEP tweezers and probes inside a microfluidic device, along with an arbitrary function generator connected to a high voltage amplifier; (2) mi...

The hydrogen bonds involving sulfur (sulfur center hydrogen bonds; SCHBs) are generally regarded as weak H-bonds in comparison with the conventional N–H· · ·O, O–H· · ·O, N–H· · ·N and O–H· · ·N H-bonds. One of the reasons being considered for this is the smaller electronegativity of S than O or N. However, recent high resolution laser spectroscopy in combination with quantum chemical calculati...
