In the title layered coordination polymer, [Sr(C8H10O4)]n, the strontium ion adopts a distorted square-antiprismatic SrO8 geometry, arising from its coordination by six different cis-cyclohexane-1,2-dicarboxylate dianions (two bidentate and four monodentate). Within the dianion, the cyclohexane ring adopts a chair conformation and the dihedral angle between the planes of the -CO2- groups is 80.4 (6)°. The polyhedral linkage pattern leads to (100) sheets in the crystal in which the SrO8 groups share triangular faces and edges in which the Sr···Sr topol. connectivity is a 63 net. The crystal studied was a nonmerohedral twin, with the components related by a 180° rotation about [100].

In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Crystal structure of the thalidomide analog (3aR*,7aS*)-2-(2,6-dioxopiperidin-3-yl)hexahydro-1H-isoindole-1,3(2H)-dione, published in 2018-11-01, which mentions a compound: 610-09-3, Name is cis-Cyclohexane-1,2-dicarboxylic acid, Molecular C8H12O4, Recommanded Product: 610-09-3.

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)].
