“…The carboxyl group is found to occur in its unsymmetrical conformation (Dunitz & Strickler, 1968) in such a way that the C=O bond is synplanar with respect to the C(2)-C(2") bond, the internal rotation angle O(2)-C(3)-C(2)-C(2") being 8 °. This conformation, recently described as 'preferred' (Dunitz & Strickler, 1968), has been observed by us in the case of the trans and cis isomers of 1,2-cyclohexanedicarboxylic acids (Benedetti, Corradini, Pedone & Post, 1968Benedetti, Pedone & Allegra, 1970). The atoms of the carboxyl group forming hydrogen bonds across symmetry centers are essentially planar.…”

“…1), is a new coordination polymer that complements the phases noted above. The cyclohexane ring of the anion in (I) adopts its typical chair conformation with normal bond lengths (Allen et al, 1987) and angles similar to those seen in related compounds (Benedetti et al, 1970;Lee et al, 2006). The C7-C1-C2-C8 torsion angle of 57.5 (7) confirms the presence of the cis isomer (also known as the axial-equatorial form; see Thirumurugan et al, 2006).…”

In the title layered coordination polymer, [Sr(C(8)H(10)O(4))](n), the strontium ion adopts a distorted square-antiprismatic SrO(8) 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 -CO(2)(-) groups is 80.4 (6) degrees. The polyhedral linkage pattern leads to (100) sheets in the crystal in which the SrO(8) groups share triangular faces and edges in which the Sr...Sr topological connectivity is a 6(3) net. The crystal studied was a nonmerohedral twin, with the components related by a 180 degree rotation about [100].
