The structure of adipic acid undergoing phase transition at &136 K has been investigated using single-crystal x-ray di4raction. On lowering the temperature, the a parameter of the room temperature monoclinic cell decreases by &0.25 A s . Accompanying the transition, the b parameter nearly triples wh
Pure polycrystalline Li 2 C 2 could be obtained by the reaction of lithium and graphite flakes in an arc-melting furnace. X-ray powder investigations on these samples confirm the crystal structure given by Juza, Wehle, and Schuster (Immm, No. 71, Z = 2) which is isotypic to Rb 2 O 2 and Cs 2 O 2 . A
