The crystal structure described by Sr4C2N5 crystallizes in the monoclinic P2_1/c space group. There are four inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a 8-coordinate geometry to one C(1), one N(1), two equivalent N(3), and four equivalent N(2) atoms. In the second Sr site, Sr(2) is bonded in a 5-coordinate geometry to one N(1), one N(2), one N(4), and two equivalent N(3) atoms. In the third Sr site, Sr(3) is bonded in a 6-coordinate geometry to one N(1), two equivalent N(4), and three equivalent N(5) atoms. In the fourth Sr site, Sr(4) is bonded in a 6-coordinate geometry to one N(3), one N(5), two equivalent N(1), and two equivalent N(4) atoms. There are two inequivalent C sites. In the first C site, C(1) is bonded in a trigonal planar geometry to one Sr(1), one N(1), one N(2), and one N(3) atom. In the second C site, C(2) is bonded in a distorted bent 120 degrees geometry to one N(4) and one N(5) atom. There are five inequivalent N sites. In the first N site, N(3) is bonded in a 1-coordinate geometry to one Sr(4), two equivalent Sr(1), two equivalent Sr(2), and one C(1) atom. In the second N site, N(4) is bonded to one Sr(2), two equivalent Sr(3), two equivalent Sr(4), and one C(2) atom to form distorted corner-sharing NSr5C octahedra. The corner-sharing octahedral tilt angles range from 36-43°. In the third N site, N(5) is bonded in a 1-coordinate geometry to one Sr(4), three equivalent Sr(3), and one C(2) atom. In the fourth N site, N(1) is bonded in a 6-coordinate geometry to one Sr(1), one Sr(2), one Sr(3), two equivalent Sr(4), and one C(1) atom. In the fifth N site, N(2) is bonded in a 6-coordinate geometry to one Sr(2), four equivalent Sr(1), and one C(1) atom. is represented by the CIF card [CIF]
