Y2Pb3N4 crystallizes in the monoclinic C2/c space group. Y(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form a mixture of distorted edge and corner-sharing YN4 trigonal pyramids. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded in a 3-coordinate geometry to one N(2) and two equivalent N(1) atoms. In the second Pb site, Pb(2) is bonded in a water-like geometry to two equivalent N(2) atoms. There are two inequivalent N sites. In the first N site, N(1) is bonded to two equivalent Y(1) and two equivalent Pb(1) atoms to form distorted edge-sharing NY2Pb2 trigonal pyramids. In the second N site, N(2) is bonded in a distorted rectangular see-saw-like geometry to two equivalent Y(1), one Pb(1), and one Pb(2) atom.
Y2Pb3N4 crystallizes in the monoclinic C2/c space group. Y(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form a mixture of distorted edge and corner-sharing YN4 trigonal pyramids. There is one shorter (2.27 Å) and one longer (2.28 Å) Y(1)-N(1) bond length. There is one shorter (2.29 Å) and one longer (2.33 Å) Y(1)-N(2) bond length. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded in a 3-coordinate geometry to one N(2) and two equivalent N(1) atoms. The Pb(1)-N(2) bond length is 2.45 Å. There is one shorter (2.32 Å) and one longer (2.38 Å) Pb(1)-N(1) bond length. In the second Pb site, Pb(2) is bonded in a water-like geometry to two equivalent N(2) atoms. Both Pb(2)-N(2) bond lengths are 2.39 Å. There are two inequivalent N sites. In the first N site, N(1) is bonded to two equivalent Y(1) and two equivalent Pb(1) atoms to form distorted edge-sharing NY2Pb2 trigonal pyramids. In the second N site, N(2) is bonded in a distorted rectangular see-saw-like geometry to two equivalent Y(1), one Pb(1), and one Pb(2) atom.
