A single crystal study of eight-layer barium managanese oxide,BaMnO3

A single crystal study of hydrothermally prepared eight-layer BaMnO₃ has been carried out which confirms the (Zhdanov notation) 121121 layer stacking scheme for the BaO₃ layers. The MnO₆ octahedra share faces in strings of four, and these strings are connected to each other by corner sharing. The compound has an hexagonal unit cell of dimensions a = 5.667 ± 0.003 and c = 18.738 ± 0.009 Å, probable space group $\text{P6}{}_3\text{mmc}\text{, Z = 8}$. Its structure has been determined from 352 independent reflections, of which 242 were considered observed, collected manually by a counter technique and refined to a conventional R value of 0.079.     

Hydrogenation of furfural with alkali-metal amalgams

The possibility of reducing furfural to furyl alcohol with potassium and sodium amalgams under the conditions of neutralizing the alkali formed with carbon dioxide has been investigated. The reduction of furfural can be directed to the predominant formation of furyl alcohol by regulating the rate of feed of furfural into the reaction vessel.
