Crystal structure of AlFe_0.95

Three Fe-deficient B2-type AlFe_{1 – δ} phases have been synthesized, and the exact crystal structure obtained from single-crystal X-ray diffraction measurements is reported for δ = 0.05.

Tetra­aqua­(ethane-1,2-di­amine-κ²N,N′)nickel(II) naphthalene-1,5-di­sulfonate dihydrate

In the title salt, [Ni(en)(H₂O)₄]²⁺·NDS²⁻·2H₂O, the Ni²⁺ cation is positioned on a twofold rotation axis and exhibits a coordination number of six. The components are connected through an extensive network of O—H⋯O and N—H⋯O hydrogen bonds, and C—H⋯π inter­actions.

meso-α,α-5,15-Bis(o-nicotinamido­phen­yl)-10,20-diphen­ylporphyrin n-hexane monosolvate

In the title porphyrin solvate, the macrocycle shows a characteristic saddle-shaped distortion.
