Hijji, Yousef; Benjamin, Ellis; Jasinski, Jerry P.; Butcher, Ray J. published the article 《Crystal structure of the thalidomide analog (3aR*,7aS*)-2-(2,6-dioxopiperidin-3-yl)hexahydro-1H-isoindole-1,3(2H)-dione》. Keywords: isoindole thalidomide analog crystal structure; crystal structure; pseudomerohedral twinning; thalidomide analogs.They researched the compound: cis-Cyclohexane-1,2-dicarboxylic acid( cas:610-09-3 ).Safety of cis-Cyclohexane-1,2-dicarboxylic acid. Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:610-09-3) here.
The title compound, C13H16N2O4, crystallizes in the monoclinic centrosym. space group, P21/c, with four mols. in the asym. unit, thus there is no crystallog. imposed symmetry and it is a racemic mixture The structure consists of a six-membered unsaturated ring bound to a five-membered pyrrolidine-2,5-dione ring N-bound to a six-membered piperidine-2,6-dione ring and thus has the same basic skeleton as thalidomide, except for the six-membered unsaturated ring substituted for the aromatic ring. In the crystal, the mols. are linked into inversion dimers by R22(8) hydrogen bonding involving the N-H group. In addition, there are bifurcated C-H···O interactions involving one of the O atoms on the pyrrolidine-2,5-dione with graph-set notation R12(5). These interactions along with C-H···O interactions involving one of the O atoms on the piperidine-2,6-dione ring link the mols. into a complex three-dimensional array. There is pseudomerohedral twinning present which results from a 180° rotation about the [100] reciprocal lattice direction and with a twin law of 1 0 0 0 [inline formula omitted] 0 0 0 [inline formula omitted] [BASF 0.044 (1)].
From this literature《Crystal structure of the thalidomide analog (3aR*,7aS*)-2-(2,6-dioxopiperidin-3-yl)hexahydro-1H-isoindole-1,3(2H)-dione》,we know some information about this compound(610-09-3)Safety of cis-Cyclohexane-1,2-dicarboxylic acid, but this is not all information, there are many literatures related to this compound(610-09-3).
