 Title    Preparation and Reactions of the T etrahedrane Molecule Fe2(CO )6(P-/m -C 4Hg)2  
 Abstract    The F e2P2 tetrahedrane com pound Fe2(CO)f,(P—fBu)2 has been obtained by oxidation of Fe2(C O)A («-PH rB u)2. D ue to its short (206 pm) P —P bond it can be called a diphosphene com ­ plex. In contrast to this the P —P bond is its principal centre o f reactivity: CO , C2H 4, and C2H 2 (with concom itant hydrogenation) are inserted, H 2 and HC1 are added with P —P cleavage, and reductive cleavage occurs with L iB H E t,. The crystal structures of the title com pound and of its CO and C2H 4 insertion products have been determ ined.

 Title    Darstellung und Eigenschaften von und Reaktionen mit metallhaltigen Heterocyclen, LII [1] Bindungs-und Strukturverhältnisse von Phosphidocobaltaten in Lösung und im festen Zustand Preparation and Properties of, and Reactions with, M etal-Containing Heterocycles, LII [1] Bonding and Structural Conditions of Phosphidocobaltates in Solution and in Solid State  
 Abstract    Reduction o f [(O C)3C oPPh2]" (la) with excess sodium granules affords [(O C)3CoPPh2]N a2 (3a) in solution as well as in solid state. H ow ever, in analogous reactions o f [(O C)3C oP R 2H ]2 (lb : R = C6H n ; lc : R = r-Bu) with excess sodium granules the m onovalent anionic com plexes [(O C)3C oP R 2H ]Na (2b, c) are obtained in TH F solution. 2 b , c cannot be isolated in solid state. A fter removal of TH F from their solutions the purified residues were identified by elem ental
