Propane-1,3-di­ammonium molybdate

The reaction between equimolar amounts of propane-1,3-di­amine and molybdenum trioxide in water led to the formation of single crystals of the title salt, (C₃H₁₂N₂)[MoO₄]. The asymmetric unit comprises of one propane-1,3-di­ammonium cation and one molybdate anion. The latter is isolated in the structure and has a slightly distorted tetra­hedral configuration. An extensive network of N—H⋯O hydrogen bonds connects anions and cations, giving rise to a compact three-dimensional packing.

2,8-Di­methyl-5,11-bis­[3-(methyl­sulfan­yl)prop­yl]-1H,7H-diimidazo[c,h][1,6]diazecine

In the crystal structure of the title compound, large voids of ca 100 ų are present, which are apparently not filled with solvent mol­ecules.

1,3-Bis(2-cyanopropan-2-yl)-5-methyl­benzene

The crystal structure of the title compound has been characterized by single-crystal X-ray diffraction and by IR, UV, and ¹H NMR spectroscopic techniques. The mol­ecule resides on a crystallographic twofold axis, which leads to disorder of the H atoms on the methyl group attached to the benzene ring.

The mol­ecular and crystal structure of a perchlorate salt of the 1,3-bis­(2,4,6-tri­methyl­phen­yl)imidazolium cation is reported.

The crystal structure of 2-[(tert-butyl­diphenyl­sil­yl)­oxy]-1,2-di­phenyl­ethan-1-one

The title compound is a benzoin with a bulky substituent on the alcohol group. The conformation in the crystal structure is similar to that found for the unsubstituted benzoin.

D-Glutamic acid hydro­chloride

The absolute structure of D-glutamic acid hydro­chloride has been determined by single-crystal X-ray diffraction at room temperature using Cu Kα radiation.

3,5-Di­chloro-3′,4′-di­meth­oxy­biphen­yl

The structure of the title compound, a di­hydroxy­lated metabolite of 3,4-di­chloro­biphenyl (PCB 14)features π–π stacking inter­actions between inversion-related chlorinated benzene rings

S,S-Di­phenyl-N-tosyl sulfone di­imine

In the title compound, the configuration around the sulfur atom of the sulfonedi­imine group is a slightly distorted tetra­hedron with two S=N bonds and two S—C bonds. In the crystal, mol­ecules are connected by pairs of N—H⋯O hydrogen bonds, forming inversion dimers with an (12) ring motif.

The title compound, a rare example of a spiro­cyclic ortho­amide, was synthesized by a double cyclization of a N-Boc protected sarcosine derivative. The crystal structure of the racemic (R,R/S,S) modification reveals two near-orthogonal five-membered heterocyclic ring systems, each in an envelope configuration.

N-(4-Chloro­phen­yl)-9H-fluoren-9-imine

In the title compound, the dihedral angle between the fluorene moiety and the chloro­phenyl ring is 64.59 (6)° and a possible weak intra­molecular C—H⋯π inter­action occurs.
