The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: cis-Cyclohexane-1,2-dicarboxylic acid(SMILESS: O=C([C@H]1[C@@H](C(O)=O)CCCC1)O,cas:610-09-3) is researched.SDS of cas: 14694-95-2. The article 《Poly[(μ6-rac-cis-cyclohexane-1,2-dicarboxylato)strontium]》 in relation to this compound, is published in Acta Crystallographica, Section C: Crystal Structure Communications. Let’s take a look at the latest research on this compound (cas:610-09-3).
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].
