(R,R/S,S)-9-Benzyl-3-methyl-7-phenyl-1,6-dioxa-3,9-di­aza­spiro­[4.4]nonane-2,8-dione

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.

Accepted 16 April 2019

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 R_{2}^{2}(12) ring motif.

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

Accepted 9 April 2019

1,1′-Bis(4-bromo­phen­yl)-3,3′-di­phenyl­ferrocene

In the title compound, [Fe(C17H12Br)2], the five-membered rings sandwiching the iron atom are almost perfectly eclipsed.

Accepted 3 April 2019

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.
