The crystal structure of Ni5-δSn4Zn (δ ∼ 0.25) is an ordered representative of the Ni2GaGe prototype exhibiting some vacancies at one Ni site. The relation of building blocks to the NiAs structure type is shown.
The crystal structure of Pb5.0(1)In8.4(1)Bi1.6(1)S20, a compositional variant of a new quaternary sulfide phase, is closely related to the structures of a ternary and another quaternary phase with very different Pb:Bi ratios.
The title compound comprises an ∊-Keggin polyoxomolybdate(V) cluster capped by four CoII centres. The use of deuterated reagents aided the growth of sufficiently large single crystals of this compound, which adopts a monoclinic structure and crystallizes in the space group P21/m.
Diammonium carbonate hydrogen peroxide monosolvate, (I), and dicaesium carbonate hydrogen peroxide trisolvate, (II), were crystallized from 98% hydrogen peroxide. The peroxide molecules in both (I) and (II) act as donors in only two hydrogen bonds with carbonate anions.
