Notable people with the surname include: Alexander Filippou (born 1958), Greek-German chemistry scholar Costas Philippou (born 1979), Greek-Cypriot-American mixed martial artist Danny and Michael Philippou, creators of Australian YouTube channel RackaRacka Efthymis Filippou (born 1977), Greek screenwriter Filippos Filippou (disambiguation) Ioánna Filíppou (born 1995), Cypriot beauty pageant competitor Mattaes Phillipou (born 2004), Australian rules footballer Michalis Filippou (born 1951), Greek football manager Nikos Filippou (born 1962), Greek basketballer Sam Phillipou (born 1974), Australian rules footballer Members of
22-400: A bond order of three. The most common triple bond is in a nitrogen N 2 molecule; the second most common is that between two carbon atoms, which can be found in alkynes . Other functional groups containing a triple bond are cyanides and isocyanides . Some diatomic molecules, such as diphosphorus and carbon monoxide , are also triple bonded. In skeletal formulae the triple bond

Triple bond A triple bond in chemistry is a chemical bond between two atoms involving six bonding electrons instead of the usual two in a covalent single bond . Triple bonds are stronger than the equivalent single bonds or double bonds , with
44-404: Is drawn as three parallel lines (≡) between the two connected atoms. Triple bonding can be explained in terms of orbital hybridization . In the case of acetylene, each carbon atom has two sp-orbitals and two p-orbitals . The two sp-orbitals are linear, with 180° bond angles , and occupy the x-axis in the cartesian coordinate system . The p-orbitals are perpendicular to the sp-orbitals on
55-596: The Humboldt-University of Berlin and in 2005 he became professor (W3) of Inorganic Chemistry at the Rheinische Friedrich-Wilhelms-Universitaet Bonn . Filippou has made a significant contribution in the research of heavier homologues of carbon (Si, Ge, Sn, Pb) regarding the ability to form a triple bond to a metal.

77-487: The overlapping of three sp lobes without the need to invoke a pi-bond. Many elements beyond oxygen can form triple bonds. These bonds are common in some transition metals. Hexa(tert-butoxy)ditungsten(III) and Hexa(tert-butoxy)dimolybdenum(III) are well known examples, in which the metal-metal bond distance is about 233 pm. Hexa(tert-butoxy)ditungsten(III) has attracted particular attention for its reactions with alkynes, leading to metal-carbon triple bonded compounds of

110-411: The y-axis and the z-axis. When the atoms approach each other, the sp orbitals overlap to form an sp-sp sigma bond . At the same time the p z -orbitals approach and together they form a p z -p z pi-bond . Likewise, the other pair of p y -orbitals form a p y -p y pi-bond. The result is formation of one sigma bond and two pi bonds. In the bent bond model , the triple bond can also formed by
