2,3-Dichlorobenzene-1,4-diol
The achiral title compound, C(6)H(4)Cl(2)O(2), crystallizes with O-H⋯O hydrogen bonding linking mol-ecules into layers. Between layers there are chains of Cl⋯Cl⋯Cl inter-actions with alternating distances of 3.274 (2) and 3.742 (2) Å. Augmenting this arrangement there are also C-H⋯Cl (2.97 and 3.17 Å) and Cl⋯π (shortest distances 3.40 and 3.54 Å) inter-actions.
متن کامل1,4-Dibromonaphthalene-2,3-diol
In the title compound (r.m.s. deviation for the non-H atoms = 0.020 Å), C(10)H(6)Br(2)O(2), an intra-molecular O-H⋯O hydrogen bond generates an S(6) ring. In the crystal, the same H atom also forms an inter-molecular O-H⋯O hydrogen bond, generating a C(2) chain propagating in [100]. The other O-H hydrogen forms a weak O-H⋯π inter-action, and short Br⋯Br contacts [3.5972 (9) Å] also occur.
متن کامل1,4-Dichloronaphthalene-2,3-diol
The achiral planar (maximum deviation 0.014 Å) title compound, C(10)H(6)Cl(2)O(2), crystallizes in the chiral space group P2(1)2(1)2(1) in an arrangement incorporating conventional O-H⋯O hydrogen bonding leading to a supra-molecular chain.
متن کامل2,2,3,3-Tetrafluorobutane-1,4-diol
In the title compound, C(4)H(6)F(4)O(2), a partially fluorinated aliphatic diol, cooperative O-H⋯O hydrogen bonds form R(2) (2)(14) rings, which are connected into infinite layers parallel to the (100) plane by C(7) chains. A C-H⋯F link is also seen.
متن کاملcis-Cycloheptane-1,2-diol
The title compound, C(7)H(14)O(2), is a vicinal diol derived from cyclo-heptane with cis-orientated hydr-oxy groups. The mol-ecules shows no non-crystallographic symmetry. The O-C-C-O torsion angles of both mol-ecules present in the asymmetric unit [-66.4 (2) and -66.9 (2)°] are similar to those in trans-configured cyclo-hexane derivatives (including pyran-oses) as well as rac-trans-cyclo-hepta...
