The structure of the title compound confirms the relative stereochemistry.

5-{[(2-Hy­droxy­eth­yl)sulfan­yl]meth­yl}quinolin-8-ol

In the title mol­ecule, the quinolinol unit is planar. In the crystal, O—H⋯N and O—H⋯S hydrogen bonds together with π-stacking inter­actions form layers parallel to [100] that are associated through C—H⋯O hydrogen bonds.

Ethyl­ammonium hydrogen oxalate–oxalic acid (2/1)

The title compound was obtained by mixing ethyl­amine and oxalic acid in water, in 1:1 molar ratio. In the crystal, the hydrogen oxalate anions are organized through hydrogen bonding into chains propagating along the c-axis direction. The surrounding cations and oxalic acid mol­ecules are linked to the chains by N—H⋯O and O—H⋯O hydrogen bonds and N⋯O dipole–dipole contacts, leading to a supra­molecular three-dimensional network.

2-Amino-5,5-di­methyl­thia­zol-4(5H)-one

The synthesis and structures of 2-amino-5,5-di­methyl­thia­zol-4(5H)-one is presented. The mol­ecular packing exhibits a herringbone pattern with the zigzag running along the b-axis direction.

(E)-N′-Hy­droxy-N,N-di­methyl-2-(3-nitro­phen­yl)­acetimidamide

In the crystal of the title amidoxime derivative, a short NO₂⋯NO₂ contact is seen.

2,3-Di­chloro-3′,4′-di­hydroxy­biphen­yl

The mol­ecular and crystal structure of 2,3-di­chloro-3′,4′-di­hydroxy­biphenyl, a putative di­hydroxy­lated metabolite of 2,3-di­chloro­biphenyl (PCB 5), is reported.

Dodecan-1-aminium sulfate trihydrate

The asymmetric unit of the title salt, (C₁₂H₂₈N)₂[SO₄]·3H₂O, contains two n-do­decyl­ammonium cations, one sulfate anion and three water mol­ecules. In the crystal, N—H⋯O hydrogen bonds link the cations and anions into layers parallel to (100). These layers are further connected through O—H⋯O hydrogen-bonding inter­actions involving the sulfate ions and the isolated water mol­ecules.
