摘要

The metallic grey compound Ba5P9 can be synthesised from the elements in stoichiometric amounts. It reacts easily with moist air. In the crystal structure (orthorhombic, Fdd2, a = 1562.6(1) pm, b = 1896.8(2) pm, c = 1027.2(2) pm; Z = 8) anionic P-9 chain fragments are separated by Ba cations. With respect to the stoichiometry a charge of 10- results for the polyphosphide anion, but 11 electrons are needed following the (8-N) rule. According to magnetic measurements the anionic unit is no radical, so a stabilisation by double bonds is discussed. [References: 12]
