The mol-ecule of the title compound, C(8)H(8)Br(2)O, is approximately planar with a maximum deviation of 0.063 (1) Å for one of the Br atoms. In the crystal, adjacent mol-ecules are joined inter-molecular O-H⋯O hydrogen bonds, forming chains parallel to [010]. The structure also features a short Br⋯Br inter-action of 3.362 (1) Å.

The asymmetric unit of the title compound, {[Co(CHO)(HO)]·2CHNO} or {[Co(Hdondc)(HO)]·2DMF} , comprises half of a Co ion, half of a 1,5-di-hydroxy-naphthalene-2,6-di-carboxyl-ate dianion (Hdondc), two water mol-ecules and a di-methyl-formamide (DMF) mol-ecule. The Co ion, which is located on a crystallographic inversion center, exhibits a distorted six-coord-inated octa-hedral geometry with two oxygen atoms of the Hdondc ligand and four oxygen atoms of the water mol-ecules. The carboxyl-ate group is almost coplanar with the naphthalene moiety and shows monodentate coordination to the Co ion.

Etoxazole (CHFNO), systematic name 4-(4--butyl-2-eth-oxy-phen-yl)-2-(2,6-di-fluoro-phen-yl)-4,5-di-hydro-1,3-oxazole, is a fluorinated insecticide and acaricide that inhibits chitin biosynthesis, disrupting insect development by preventing proper exoskeleton formation. Widely used in agriculture since 1998, it is readily absorbed by plant tissues and translocates within leaves. Metabolic studies have identified several oxidative degradation products, while toxicol-ogical assessments have examined potential effects, including oxidative stress.

The title compounds, [Ce(CHSO)(CHSO)(CHCOOH)] () and [Ce(CHCOO)(CHSO)(HO)] () were synthesized by solvothermal reaction of Ce(NO)·6HO with 2,5-thio-phenedi-carb-oxy-lic acid (HTDC, CHSO) and acetic acid in aceto-nitrile or ethanol/water, respectively. These compounds were obtained as single crystals among other crystalline phases. Both compounds belong to the family of three-dimensional coordination polymers.

The asymmetric units of -poly[[(1,4,8,11-tetra-aza-cyclo-tetra-decane-κ , , , )nickel(II)]-μ-sulfato-κ : ], [Ni(SO)(CHN)] (), and -poly[[(1,4,8,11-tetra-aza-cyclo-tetra-decane-κ , , , )nickel(II)]-μ-sul-fato-κ : ] hemi[4,4',4'',4'''-(2,2',4,4',6,6'-hexa-methyl-[1,1'-biphen-yl]-3,3',5,5'-tetra-yl)tetra-benzoic acid] nona-hydrate], {[Ni(SO)(CHN)]·CHO·18HO} (), consist of two crystallographically unique centrosymmetric macrocyclic dications and a sulfate dianion. In it includes additionally a mol-ecule of the undissociated acid (2,2',4,4',6,6'-hexa-meth-yl[1,1'-biphen-yl]-3,3',5,5'-tetra-yl)tetra-(benzoic acid) located on a crystallographic twofold axis and nine highly disordered water mol-ecules of crystallization. In both compounds, the metal ions are coordinated in the equatorial plane by the four secondary N atoms of the macrocyclic ligand, which adopts the most energetic-ally stable -III conformation.
