Abstract:
The short thermolysis of the butterfly molecule [{Cp'''(OC)2 Fe}2 P4 ] affords, besides [Cp'''FeP5 ] and [{Cp'''Fe}2 P4 ], the diphosphadiferratetrahedrane [{Cp'''Fe}2 (μ-CO)(μ-η2 :η2 -P2 )] with a Fe-Fe double bond in 18 % yield. The P2 building block was split photochemically into two μ-P ligands with elimination of CO. In the resulting dinuclear complex 1, the 31 P NMR signal is shifted to extremely low field (δ=1406.9), and the rhombic Fe2 P2 four-membered ring is almost orthogonal to the eclipsed Cp''' five-membered rings; Cp'''=tBu3 C5 H2 .

Structure and Bonding of Alkenes
Doubly bonded carbons are sp2 hybridized and have a trigonal planar geometry. The double bond is composed of a σ bond formed by the overlap of hybrid orbitals and a π bond produced by the lateral overlap of unhybridized 2p orbitals on both the carbons. Each carbon atom is...
