Titanium vanadium nickel, TiV_0.08Ni_0.92

A single-crystal of the inter­metallic phase TiV_0.08Ni_0.92 was obtained by the high-temperature sinter­ing of a mixture of nominal composition Ti_0.9V_0.1Ni. The title compound adopts the CsCl structure type with one site solely occupied by Ti and the other by V and Ni with a ratio of 0.08 (7):0.92 (7).

Poly[[bis­(μ₄-acetato-κ⁴O:O:O′:O′)tetra­kis­(μ₃-acetato-κ³O:O:O′)bis­(μ₂-acetato-κ²O:O′)bis­(μ₃-hydroxido)penta­nickel(II)] 2.60-hydrate]

The basic nickel acetate [Ni₅(OAc)₈(OH)₂]·2.60H₂O crystallizes in a polymeric framework structure with all three unique nickel cations in octa­hedral coordination by O atoms.

Bis{4-(all­yloxy)-N′-[4-(oct­yloxy)benzyl­idene]benzohydrazidato}nickel(II)

A bis­chelated mononuclear nickel(II) complex with benzohydrazide ligands bearing an all­yloxy group and a long saturated alkyl chain is reported.

4-(4-tert-Butyl­benz­yl)-1-neo­pentyl-1,2,4-triazolium bromide

The title 1,2,4-triazolium salt, C₁₈H₂₈N₃⁺·Br⁻, crystallizes in the monoclinic space group Pc. The extended structure exhibits a short inter­molecular inter­action between a heterocyclic C—H group and a bromide ion. Additional weaker inter­actions exist between the other heterocyclic C—H group, an alkyl C—H group and bromide ions.

3-(2-Eth­oxy-2-oxoeth­yl)-4,5,6,7,8,9-hexa­hydrocyclo­octa­[d][1,2,3]selena­diazol-3-ium bromide

The title compound features a selena­diazole five-membered ring attached to a cyclo­octene ring. A bromine anion is located in the vicinity of the selenium atom [3.0197 (5) Å].

2-Oxo-2H-chromen-7-yl 3-methyl­butano­ate

In the crystal, mol­ecules form centrosymmetric hydrogen-bonded dimers through pairwise C—H⋯O inter­actions, generating R₂²(8) and R₂²(18) loops that lie within the crystallographic ac plane and propagate along the [001] direction.

2,2′-[(4-But­oxy­phen­yl)methyl­ene]bis­(3-hy­droxy-5,5-di­methyl­cyclo­hex-2-en-1-one)

In the title compound, C₂₇H₃₆O₅, both the cyclo­hexenone rings adopt envelope conformations.
