Y2Zn3N4 crystallizes in the monoclinic C2/c space group. Y(1) is bonded in a 6-coordinate geometry to three equivalent N(1) and three equivalent N(2) atoms. There are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded in a distorted trigonal non-coplanar geometry to one N(2) and two equivalent N(1) atoms. In the second Zn site, Zn(2) is bonded in a bent 150 degrees geometry to two equivalent N(2) atoms. There are two inequivalent N sites. In the first N site, N(1) is bonded to three equivalent Y(1) and two equivalent Zn(1) atoms to form a mixture of distorted edge and corner-sharing NY3Zn2 trigonal bipyramids. In the second N site, N(2) is bonded to three equivalent Y(1), one Zn(1), and one Zn(2) atom to form a mixture of distorted edge and corner-sharing NY3Zn2 trigonal bipyramids.
Y2Zn3N4 crystallizes in the monoclinic C2/c space group. Y(1) is bonded in a 6-coordinate geometry to three equivalent N(1) and three equivalent N(2) atoms. There are a spread of Y(1)-N(1) bond distances ranging from 2.36-2.43 Å. There are a spread of Y(1)-N(2) bond distances ranging from 2.40-2.80 Å. There are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded in a distorted trigonal non-coplanar geometry to one N(2) and two equivalent N(1) atoms. The Zn(1)-N(2) bond length is 1.97 Å. There is one shorter (1.98 Å) and one longer (2.11 Å) Zn(1)-N(1) bond length. In the second Zn site, Zn(2) is bonded in a bent 150 degrees geometry to two equivalent N(2) atoms. Both Zn(2)-N(2) bond lengths are 1.84 Å. There are two inequivalent N sites. In the first N site, N(1) is bonded to three equivalent Y(1) and two equivalent Zn(1) atoms to form a mixture of distorted edge and corner-sharing NY3Zn2 trigonal bipyramids. In the second N site, N(2) is bonded to three equivalent Y(1), one Zn(1), and one Zn(2) atom to form a mixture of distorted edge and corner-sharing NY3Zn2 trigonal bipyramids.
