Abstract The crystal structure of [C4H10NO][BF4] is determined in the phase I at 160, 180, 240 and 290 K. At room temperature the compound crystallizes in the orthorhombic space group: Pnam. TheExpand
The quasi-symmetric OHN and ODN bridges in the adducts of 3,5-dimethylpyridine with 3,5-dinitrobenzoic acid
Abstract The crystal structure of the adduct of 3,5-dimethylpyridine and 3,5-dinitrobenzoic acid (DMP-DNB) has been determined at room temperature and 80 K for both undeuterated and deuteratedExpand
Synthesis and antibacterial properties of pyrimidine derivatives.
The paper presents the synthesis of 1,2,3,7-tetraaryl-1,2,3,4-tetrahydropyrimido[4,5-d]pyrimidines. The structures of the obtained compounds were confirmed by crystallographic and spectroscopicExpand
The low-temperature phase of morpholinium tetrafluoroborate
The crystal structure of the low-temperature form of the title compound, C4H10NO+·BF4 −, consists of three BF4 − tetrahedral anions and three morpholinium cations (Z′ = 3). Expand
4,4′-Bipyridine–butane-1,2,3,4-tetracarboxylic acid (1/1)
The title compound, C10H8N2·C8H10O8, is a 1:1 adduct between 4,4′-bipyridine and butane-1,2,3,4-tetracarboxylic acid, where both components are centrosymmetric. Expand
Cyclic water pentamers in triclinic crystals of brucinium L-glycerate.
Brucinium L-glycerate 4.75-hydrate, C23H27N2O4+.C3H5O4-.4.75H2O, was obtained by racemic resolution of DL-glyceric acid. This is the first report of triclinic crystals containing brucine. The waterExpand
The structure of O-phospho-DL-threonine in potassium, sodium and ammonium environments
Summary Interactions of O-phospho-DL-threonine (DL-PThr) in the different ionization states with potassium, sodium and ammonium cations have been studied on five crystals (denoted as I-V). InExpand
