Mg_20.66Al_12.24Zn_20.04

The title single-crystal (icosa­magnesium dodeca­aluminium icosa­zinc), was obtained during the synthesis of an Mg–Al–Zn alloy at high pressure and temperature. There are significant difference between the current model and that of previous studies.

Nonamagnesium diruthenium, Mg₉Ru₂

A monoclinic ordered Mg₉Ru₂ phase with C2/c space-group symmetry rather than previously reported cubic Mg₄₄Ru₇ or Mg₃Ru₂ was obtained via high-pressure sinter­ing during the effort of synthesizing a target Mg—Ru—B compound.

CaCu_1.424Fe_0.576Si₂

A CaCu_1.424Fe_0.576Si₂ phase was obtained during high-pressure sinter­ing of an Si-rich quasicrystal composition prealloy with the nominal chemical com­position Si₆₁Cu₃₀Ca₇Fe₂. The obtained phase crystallizes in the space group I4/mmm (No. 139), with a = b = 4.041 Å and c = 10.010 Å.

(Nitrito-κ²O:O′)bis­[tris­(4-fluoro­phen­yl)phosphine-κP]silver(I)

The significant structural feature in the title Ag^I complex is the small bite angle of the nitrito ligand [49.80 (5)°], which influences the overall geometry.

(E)-N-[4-(Di­ethyl­amino)-2-hy­droxy­benzyl­idene]-2,4,6-tri­methyl­benzenaminium nitrate

The crystal structure of a protonated Schiff base, isolated as its nitrate salt, exhibits a supra­molecular chain-like architecture that propagates along the crystallographic b-axis direction and features inter­molecular O—H⋯O and C—H⋯O hydrogen-bonding.
