A 60-year-old problem with the atomic arrangements and exact compositions of alkali polytungstates related to hexagonal tungsten bronze (HTB) was solved. The systems WO-WO ( = K, Rb) were restudied and the average monoclinic layered structures of stoichiometric polytungstates WO ( = K, Rb, Cs, Tl) and WO ( = K, Rb, Cs) were first successfully determined. The structures resemble those of "MoWO" and "MoWO" (J.

The co-crystallisation of [NiEn](NO) (En = ethylenediamine) with NaMoO and NaWO from a water solution results in the formation of [NiEn](MoO)(WO) co-crystals. According to the X-ray diffraction analysis of eight single crystals, the parameters of the hexagonal unit cell (space group -31, = 2) vary in the following intervals: a = 9.2332(3)-9.

Separation of structurally similar components from their mixtures is one of the most promising applications of metal-organic frameworks (MOFs). A high efficiency of such molecular sieving requires fine tuning of the MOF structure. In this work, we investigate subtle metal- and temperature-induced changes in window dimensions of zeolitic imidazolate frameworks (ZIF-8(Zn) and ZIF-67(Co)) and apply such structural tuning for efficient separation of xylene isomers (-, -, and -xylenes).

Rhodium(III) octahedral complexes with amine and chloride ligands are the most common starting compounds for preparing catalytically active rhodium(I) and rhodium(III) species. Despite intensive study during the last 100 years, synthesis and crystal structures of rhodium(III) complexes were described only briefly. Some [RhCl(NH)] compounds are still unknown.
