The material structure described by Sr3(BN2)2 crystallizes in the monoclinic C2/c space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a 3-coordinate geometry to one N(1) and two equivalent N(2) atoms. In the second Sr site, Sr(2) is bonded in a 6-coordinate geometry to two equivalent N(2) and four equivalent N(1) atoms. B(1) is bonded in a distorted trigonal planar geometry to one N(2) and two equivalent N(1) atoms. There are two inequivalent N sites. In the first N site, N(1) is bonded in a 2-coordinate geometry to one Sr(1), two equivalent Sr(2), and two equivalent B(1) atoms. In the second N site, N(2) is bonded in a 1-coordinate geometry to one Sr(2), two equivalent Sr(1), and one B(1) atom. is represented by the CIF card [CIF]
