title: Tris(2-pyridyl)phosphine oxide: how C-H.O and C-H.N interactions can affect crystal packing efficiency.
abstract: Tris(2-pyridyl)phosphine oxide, (I), C(15)H(12)N(3)OP, is isomorphous with tris(2-pyridyl)phosphine. Because of a combination of C-H.O and C-H.N interactions, the crystal packing is denser in the title compound than in the related compounds triphenylphosphine oxide and tris(2-pyridyl)phosphine.
