The Al_61.49Mn_11.35Ni₄ phase in the Al–Mn–Ni system

The Al_61.49Mn_11.35Ni₄ phase was synthesized by high-temperature sinter­ing and its crystal structure has been re-determined.

Bis­(di­methylamine-κN)bis­[4-(1,2,4-triazol-1-yl)benzoato-κO]copper(II)

A three-dimensional supermolecule based on 4-(1,2,4-triazol-1-yl)benzoic acid was prepared under solvothermal conditions. In the crystal, inter­molecular N—H⋯N hydrogen bonds between the amine function and the central N atom of the triazole ring lead to the formation of ribbons parallel to [11].

[Sulfonyl­bis­(bromo­methyl­ene)]di­benzene

The title compound crystallizes as the mesomeric isomer, which helped establish that the 1,3 elimination of bromine by tri­phenyl­phosphine occurs with inversion of configuration at each chiral carbon atom.

β-D-Galacto­pyranosyl-(1→4)–2-amino-2-de­oxy-α-D-gluco­pyran­ose hydro­chloride monohydrate (lactosamine)

The amino­disaccharide adopts a conformation close to that of the parent α-lactose and is immersed in an extensive hydrogen-bonding network.

N-Phenyl-N-[(E)-2-(4,4,5,5-tetra­methyl-1,3,2-dioxaborolan-2-yl)ethen­yl]aniline

The title compound features a polarized π-system due to resonance between the N—C(H)=C(H)—B and ionic N⁺=C(H)—C(H)=B⁻ canonical forms.
