Catalytic Oxidation of Cyclohex-2-enol at Porous Iron Zeolite-like Material: Investigations by GC/MS, Polarography and X-ray Powder Diffraction

The polymeric complexes of porous iron phosphates (NH4)4Fe3II(OH)2F2[H3(PO4)4] (1), (C3H12N2) FeII6(H2O)4[B4P8O23(OH)8] (2), and {[FeII(H2PO4)2-(μ4,4'-bipy)(H2O)]·H2O·(4,4'-bipy)} (3) were successfully tested towards oxidation of cyclohex-2-enol.

Crystal Structure of the Ternary Compound ErRe0.25Ge2

An alloy of nominal composition Er30.8Re7.7Ge61.5 was synthesized by arc melting and investigated by X-ray powder diffraction. A new ternary germanide of approximate composition ErRe0.25Ge2 was found, which adopts the structure type CeNiSi2 (Pearson symbol oS16, space group Cmcm, a = 4.0997(4), b = 15.7348(18), c = 3.9921(5) Å, RB = 0.0355, refined composition ErRe0.23(2)Ge2, for the as-cast alloy; a = 4.1117(3), b = 15.6846(15), c = 4.0184(3) Å, RB = 0.0420, refined composition ErRe0.28(2)Ge2, after annealing at 1073 K).
