Bis(N,N-diethyl-N'-benzoylselenoureato)lead(II) has been prepared and characterized by single-crystal structure analysis.Pb(C12H15N2OSe)2 crystallizes in the non-centrosymmetric orthorhombic space group Iba2.The cell parameters are a = 13.206(3), b = 20.542(4), c = 10.089(2) Angstroem and Z = 4, R = 0.025.The direction of the polar axis was determined unambiguously.Pb(II) is bidentally coordinated to two N,N-diethyl-N'-benzoylselenourea molecules.The coordination polyhedron is a distorted pseudo-trigonal bi-pyramid with one equatorial position occupied by an electron lone-pair.The Pb-Se and Pb-O bond lengths are 2.876(1) and 2.444(4) Angstroem, respectively.In the crystal lattice, each Pb atom also shows interactions with two Se atoms of a neighboring molecule.The Pb-Se distance of that interaction is 3.643 Angstroem. - Keywords: Subvalent Main Group Metals, Bis(N,N-diethyl-N'-benzoylselenoureato)lead(II), Crystal Structure
