 Title    Ein Oxometallat mit eindimensional flächenverknüpften Oktaederketten Synthesis and Crystal Structure of (C u,Fe)363M o3O i2. An Oxom etallate Showing One-Dimensional Chains of Face Sharing Octahedra  
 Abstract    Single crystals of (C u ,F e)3-63M o30 12 have been prepared by crystallisation from melts. X-ray investigations lead to orthorhombic symmetry, space group D : 2-P 2 12121, a = 5.0952(8), b = 10.637(2), c = 17.881(3) A , Z = 4. (C u ,F e)363M o3O i2 is isotypic to Cu385M o30 12 or (C u,Z n)3 75M o30 12. M olybdenum shows tetrahedral coordination by oxygen. Cu+ and Fe2+ are probably distributed statistically over four different point positions. Interesting features of the crystal structure are one-dim ensional chains of face shared (C u ,F e)0 6 octahedra.

 Title    Photoredox Decomposition of [Cobalamin-^-NC-Fen(CN)5]3* Induced by Metal-to-Metal Charge Transfer Excitation  
 Abstract    In the presence of oxygen aqueous solutions of the binuclear complex [cobalamin-^-NC-Fe(C N)5]3' undergo a redox photolysis (0 ~ 2 x 10'3 at Airr = 405 nm) which yields aquocoba-lamin and [Fe(C N)6]3\ It is suggested that this photoreaction is induced by direct metal-to-metal charge transfer (M M CT) excitation. On the contrary, [cobalamin-fx-NC-Ru(CN)5]3' is photo-inert because a reactive MMCT state is not accessible.
