Benzene-1,4-dicarboxylic acid–N,N-dimethylacetamide (1/2)
The asymmetric unit of title compound, C(8)H(6)O(4)·2C(4)H(9)NO, contains one half-mol-ecule (an inversion centre in P21/n generates the other half of the molecule) of terephthalic acid (TA) and one mol-ecule of N,N-dimethyl-acetamide (DMAC). The DMAC mol-ecules are linked to TA by strong O-H⋯O hydrogen bonds.
متن کامل1-Hydroxymethyl-3,12-dioxa-14-azatetracyclo[9.2.1.04,14.05,10]tetradecane
In the title fused-ring compound, C(12)H(13)NO(3), the two five-membered C(3)NO rings both approximate to envelope conformations with C atoms in the flap positions. The OH group of the pendant CH(2)OH unit is disordered over two positions in a 0.528 (5):0.472 (5) ratio. One of the OH groups participates in an O-H⋯N hydrogen bond, generating centrosymmetric dimers in the crystal structure.
متن کامل1,1′-Binaphthyl-2,2′-dicarboxylic acid–urea (1/1)
In the title co-crystal, C(22)H(14)O(4)·CH(4)N(2)O, the 1,1'-binaphthyl-2,2'-dicarboxylic acid (BNDA) and urea mol-ecules are connected via a system of hydrogen bonds into a chiral two-dimensional polymeric structure parallel to the (001) plane. As the crystal is centrosymmetric, it consists of alternately stacked BNDA-urea layers of opposite chirality. The urea H atoms trans to the C=O group a...
متن کاملAcid production by oral strains of Candida albicans and lactobacilli.
Both Candida albicans and lactobacilli are common colonizers of carious lesions in children and adolescents. The purpose of this study is to compare the velocity of acid production between C. albicans and several Lactobacillus species at different pH levels and concentrations of glucose. Washed, pure resting-cell suspensions were obtained by culturing a total of 28 oral isolates comprising the ...
متن کاملAscorbic Acid Dehydroascorbic Acid C6 Dicarboxylic Acid
Dehydroascorbic acid is shown to be converted to 2-(threo-l,2,3-trihydroxypropyl)tartronic acid in aqueous alkaline solutions. The structure of the acid was determined by mass spectrometry of its acyclic Me3Si derivative. Mass spectrometric and chromatographic data are compared with those of related compounds. The acid is formed by a benzilic acid rearrangement of the intermediate 2,3-hexodiulo...
