Aqua­bis­(1,1,1,5,5,5-hexa­fluoro­acetyl­acetonato)[4′-(4-pyrid­yl)-2,2′:6′,2′′-terpyridine]­ytterbium(III) chloride methanol monosolvate monohydrate

The title compound, [Yb(C₅HF₆O₂)₂(C₂₀H₁₄N₄)(H₂O)]Cl·CH₃OH·H₂O, adopts an eight-coordinated geometry around the Yb^III atom consisting of a 4′-(4-pyrid­yl)-2,2′:6′,2′′-terpyridine (pytpy) ligand, two 1,1,1,5,5,5-hexa­fluoro­acetyl­acetonate (hfac) anions and an aqua ligand. In the solid state, the compound forms supra­molecular chains running along the b-axis via inter­molecular hydrogen bonds between the Yb—OH₂ unit and the N-atom donor of the 4-pyridyl pendant of pytpy, with an O...N distance of 2.686 (4) Å. A chloride counter-anion and lattice methanol and water solvent mol­ecules occupy a hydro­philic columnar space along the coordination chains. O—H...Cl hydrogen bonds occur. The two water molecules and the four trifluoromethyl groups are disordered over two sets of sites, each with different occupancy ratios.

Bis(2-amino­benzothia­zol-3-ium) bis­(7-oxabicyclo­[2.2.1]heptane-2,3-dicarboxyl­ato-κ³O²,O³,O⁷)zincate hexa­hydrate

In the title hydrated mol­ecular salt, (C₇H₇N₂S)₂[Zn(C₈H₈O₅)₂]·6H₂O, which is isotypic with its Mn^II, Co^II and Ni^II analogues, the Zn²⁺ ion lies on a crystallographic inversion centre and a distorted ZnO₆ octa­hedral coordination geometry arises from the two doubly deprotonated O,O′,O′′-tridentate ligands. In the crystal, the components are linked by N—H...O_a, N—H...O_w, O_w—H...O_a and O_w—H...O_w hydrogen bonds (w = water and a = anion).

3-(3,4-Dihydroxyphenyl)-1-methoxy-1-oxopropan-2-aminium chloride

In the title compound, C₁₀H₁₄NO₄⁺·Cl⁻, the benzene ring makes a dihedral angle of 64.68 (4)° with the methyl­amino­propano­ate unit, which is bonded to the catechol ring via a methyl­ene C atom. A strong intra­molecular O—H...O hydrogen bond occurs. In the crystal, O—H...O, N—H...Cl and O—H...Cl hydrogen bonds and weak C—H...O inter­actions link the mol­ecules into a three-dimensional network.
