2-(2-Hy­droxy-2-phenyleth­yl)-1-methyl­cyclo­propan-1-ol

The asymmetric unit of the title compound, C₁₂H₁₆O₂, contains two independent mol­ecules in which the dihedral angles between the benzene and cyclo­propane rings are 75.9 (3) and 76.3 (3)°. In the crystal, the mol­ecules are connected by O—H...O hydrogen bonds into a three dimensional supra­molecular structure.

Poly[[diaqua­tris(μ₂-4,4′-bi­pyridine)­bis[μ₂-2-(carb­oxylato­methyl­sulfan­yl)nicotinato]dicobalt(II)] 1.3-hydrate]

The title complex, [Co₂(C₈H₅NO₄S)₂(C₁₀H₈N₂)₃(H₂O)₂]·1.3H₂O, was synthesized under hydro­thermal conditions. The Co^II ion is six-coordinated in a slightly distorted octa­hedral environment resulting from two carboxyl­ate O atoms of two 2-carb­oxy­methyl­sulfanyl nicotinate (2-CMSN²⁻) anions, one water mol­ecule and three N atoms of three 4,4′-bi­pyridine ligands, with one 4,4′-bi­pyridine ligand situated on a centre of inversion. Two neighboring Co^II ions are linked by two anions, giving a dinuclear [Co₂(2-CMSN)₂] subunit with a Co...Co separation of 6.8600 (3) Å. The dinuclear subunits are joined by bridging 4,4′-bi­pyridine linkers, generating a three-dimensional network structure. Disordered water mol­ecules are situated in the free space of this network. O—H...O hydrogen bonding within and between the subunits enhances the stability of the structure.
