| X -ray, yr-Cycloheptatrienyl M olybdenum D icarbonyl T richlorostannyl, Crystal Structure T he structure o f the title com pound has been determ ined from three dim ensional X -ray data b y P atterson and Fourier m ethods. T he crystals are orthorom bic, w ith unit cell dim en sions a = 1181,50 pm , 6 = 943,68 pm , c = 1181,50 pm , space group D|j> and Z — 4. L east squares refinem ent, b y use o f 1540 independent reflections m easured on a diffractom eter has reached R = 5,9% . There are discrete C7H 7Mo(CO)2 SnCl3 m olecules, th e m olybdenum -tin bond has been dicussed together w ith th e corresponding bonds in other C7H ,M o(CO)2 S n R 3 compounds. | | |

| Zur Kenntnis der Erdalkaliantimonide und -wismutide Sr2Bi, Ba2Sb, Sr5Bi3, Ba5Sb3 und Ba5Bi3  | | | Abstract
| On the Earth-Alkali-A ntim onides and Bismutides Sr2Bi, B a2Sb, Sr5Bi3, B a5Sb3 and B a5Bi3 B r i g i t t e E i s e n m a n n und K l a u s D e l l e r The new compounds Sr2Bi, B a2Sb, Sr5B i3, B a5Sb3 and Ba5B i3 were prepared and their structures determined. The A 2B-compounds crystallize tetragonal bodycentered and are isotypic to Ca2Sb, Ca2Bi and Sr2Sb. The A5B 3-compounds build up the Mn5Si3-structure type. In both structures the element (V) atoms are coordinated only to earth alkali atoms. | | |

| Chromic Acid Oxidation o f Lactic Acid Catalysed by M anganese(II)  | | | Abstract
| M anganese (II), Chromic A cid, L actic Acid M n(II) ion catalysis in th e oxid ation o f lactic acid b y chromic acid has been in vestigated betw een th e p H range 2.0 to 4.0; [H+] = 0.1 to 0.4 and [H+] > 1.1 M. A ctivation para m eters for catalysed and u n catalysed reactions have been evaluated. W hile C— H bond rupture occurs in th e un catalysed reaction, th e rate lim iting step of th e catalysed reaction involves C-C bond fission. | | |
