LaN3 crystallizes in the monoclinic P2_1/c space group. There are two inequivalent La sites. In the first La site, La(1) is bonded in a 3-coordinate geometry to one N(4), one N(5), two equivalent N(3), and two equivalent N(6) atoms. In the second La site, La(2) is bonded in a 7-coordinate geometry to one N(2), one N(3), one N(6), two equivalent N(1), and two equivalent N(5) atoms. There are six inequivalent N sites. In the first N site, N(1) is bonded in a 4-coordinate geometry to two equivalent La(2), one N(5), and one N(6) atom. In the second N site, N(2) is bonded in a distorted bent 150 degrees geometry to one La(2) and one N(4) atom. In the third N site, N(3) is bonded in a distorted trigonal non-coplanar geometry to one La(2) and two equivalent La(1) atoms. In the fourth N site, N(4) is bonded in a distorted water-like geometry to one La(1) and one N(2) atom. In the fifth N site, N(5) is bonded in a rectangular see-saw-like geometry to one La(1), two equivalent La(2), and one N(1) atom. In the sixth N site, N(6) is bonded in a 4-coordinate geometry to one La(2), two equivalent La(1), and one N(1) atom.
