RbYN4 crystallizes in the triclinic P-1 space group. Rb(1) is bonded in a 7-coordinate geometry to one N(2), two equivalent N(1), two equivalent N(3), and two equivalent N(4) atoms. Y(1) is bonded to one N(3), one N(4), two equivalent N(1), and two equivalent N(2) atoms to form distorted edge-sharing YN6 pentagonal pyramids. There are four inequivalent N sites. In the first N site, N(1) is bonded in a 4-coordinate geometry to two equivalent Rb(1) and two equivalent Y(1) atoms. In the second N site, N(2) is bonded in a distorted trigonal non-coplanar geometry to one Rb(1) and two equivalent Y(1) atoms. In the third N site, N(3) is bonded in a 3-coordinate geometry to two equivalent Rb(1) and one Y(1) atom. In the fourth N site, N(4) is bonded in a distorted trigonal non-coplanar geometry to two equivalent Rb(1) and one Y(1) atom.
