Bis(l-serinium) oxalate dihydrate: polymorph II

A corrected and improved structure of the polymorph II of 2C3H8NO3 (+)·C2O4 (2-)·2H2O, based on single-crystal data, is presented. The structure is refined with anisotropic displacement parameters for all non-H atoms and all H atoms are located. Due to the charged moieties, the structure is classified as a mol-ecular salt. Inter-molecular O-H⋯O(-), O-H⋯O and N(+)-H⋯O(-)hydrogen bonds link the c...

Crystal Structure of L-Histidinium 2-Nitrobenzoate

A new nonlinear optical organic compound, namely, L-histidinium 2-nitrobenzoate (abbreviated as LH2NB (I); ([C(6)H(10)N(3)O(2)](+) [C(7)H(4)NO(4)](-))), was synthesized. The molecular structure of LH2NB (I) was elucidated using single crystal X-ray diffraction technique. The second harmonic generation (SHG) efficiency of this compound is about two times that of the standard potassium dihydrogen...

Crystal structure of seleno-l-cystine di­hydro­chloride

Numerous crystal structures are available for the dimeric amino acid cystine. In proteins it is formed by oxidation of the -SH thiol groups of two closely spaced cysteine residues, resulting in the formation of a familiar di-sulfide bridge. The title compound [systematic name: (R,R)-1,1'-dicarb-oxy-2,2'-(diselanedi-yl)diethanaminium dichloride], C6H14N2O4Se2 (2+)·2Cl(-), is the first example of...

Crystal structure of β-d,l-fructose

The title compound, C6H12O6, was crystallized from an aqueous solution of equimolar mixture of d- and l-fructose (1,3,4,5,6-penta-hydroxy-hexan-2-one, arabino-hexulose or levu-lose), and it was confirmed that d-fructose (or l-fructose) formed β-pyran-ose with a (2) C 5 (or (5) C 2) conformation. In the crystal, two O-H⋯O hydrogen bonds between the hy-droxy groups at the C-1 and C-3 positions, a...

Crystal structure of β-d,l-allose

The title compound, C6H12O6, a C-3 position epimer of glucose, was crystallized from an equimolar mixture of d- and l-allose. It was confirmed that d-allose (l-allose) formed β-pyran-ose with a (4) C 1 ((1) C 4) conformation in the crystal. In the crystal, molecules are linked by O-H⋯O hydrogen bond, forming a three-dimensional framework. The cell volume of the racemic β-d,l-allose is 739.36 (3...
