Na2[B18Se16 ]: The First 3D Polymeric Selenoborato-closo-dodecaborate. — The
new title compound is prepared by solid state reaction of Na2Se, amorphous boron and
Se (evacuated carbon-coated silica tubes, 900 °C, 4 h). Na2[B18Se16] crystallizes in the
trigonal space group P3 with Z = 3. The compound consists of a icosahedral B12 cluster
completely saturated with trigonal-planar BSe3 units and Na+ ions. The cluster units are
connected to each other via seleno- and perselenobridges resulting in a three-dimensional network. — (HAMMERSCHMIDT, A.; DOECH, M.; PUETZ, S.; KREBS*, B.;
