Quadruple bond electrons (σπδδ*) has an Os–Os triple bond and a staggered geometry. Many other compounds with quadruple bonds between transition metal atoms have been described, often by Cotton and his coworkers. Isoelectronic with the dirhenium compound is the salt K[MoCl] (potassium octachlorodimolybdate). An example of a ditungsten compound with a quadruple bond is ditungsten tetra(hpp). Quadruple bonds between atoms of main group elements are unknown. Molecular orbital theory shows that there are two sets of paired electrons in the sigma system (one bonding, one antibonding), and two sets of paired electrons in a degenerate π-bonding set of orbitals. This adds up
The Communist Party USA and African Americans did not establish any lasting relations with the Black Panther Party, which was largely destroyed by the early 1970s, and did not recruit any significant number of members from those organizations or win them to its politics. The party maintained some standing in the black community through its former allies, including Coleman Young of Detroit and Gus Newport in Berkeley, California, who were elected to office in the 1970s.
