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
Owned-and-operated television stations in the United States stations were subsequently acquired by the Sinclair Broadcast Group; WLWC, in turn, has since been spun off to OTA Broadcasting, LLC. In June 2010, CBS announced the sale of its Norfolk, Virginia CW O&O WGNT (channel 27) to Local TV, then owner of that market's CBS affiliate WTKR-TV (channel 3) (as well as seven former Fox O&O stations). This created the second television duopoly in that market (the first involved LIN TV-owned NBC affiliate WAVY-TV (channel 10) and Fox affiliate WVBT (channel 43)). As part of the deal, Local TV would take over the operations of WGNT through a time
