Quadruple bond Quadruple bond A quadruple bond is a type of chemical bond between two atoms involving eight electrons. This bond is an extension of the more familiar types double bonds and triple bonds. Stable quadruple bonds are most common among the transition metals in the middle of the d-block, such as rhenium, tungsten, molybdenum and chromium. Typically the ligands that support quadruple bonds are π-donors, not π-acceptors. Chromium(II) acetate, Cr("μ"-OCCH)(HO), was the first chemical compound containing a quadruple bond to be synthesized. It was described in 1844 by E. Peligot, although its distinctive bonding was not recognized for more than a
WFPG-TV WFPG-TV WFPG-TV was one of the earliest UHF television stations in the United States, licensed to Atlantic City, New Jersey. The station broadcast over channel 46 from December 1952 until May 1954, and held affiliations with all four major networks of the era: NBC, CBS, ABC and DuMont.
