Sr(MnN)2 crystallizes in the monoclinic C2/m space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a 4-coordinate geometry to four equivalent N(1) atoms. In the second Sr site, Sr(2) is bonded in a 4-coordinate geometry to four equivalent N(1) atoms. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded in a distorted trigonal non-coplanar geometry to one N(2) and two equivalent N(1) atoms. In the second Mn site, Mn(2) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form distorted edge-sharing MnN4 trigonal pyramids. There are two inequivalent N sites. In the first N site, N(1) is bonded to one Sr(2), two equivalent Sr(1), one Mn(2), and two equivalent Mn(1) atoms to form a mixture of distorted edge and corner-sharing NSr3Mn3 octahedra. The corner-sharing octahedral tilt angles range from 0-86°. In the second N site, N(2) is bonded in a distorted rectangular see-saw-like geometry to two equivalent Mn(1) and two equivalent Mn(2) atoms.
Sr(MnN)2 crystallizes in the monoclinic C2/m space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a 4-coordinate geometry to four equivalent N(1) atoms. There are two shorter (2.61 Å) and two longer (2.71 Å) Sr(1)-N(1) bond lengths. In the second Sr site, Sr(2) is bonded in a 4-coordinate geometry to four equivalent N(1) atoms. All Sr(2)-N(1) bond lengths are 2.63 Å. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded in a distorted trigonal non-coplanar geometry to one N(2) and two equivalent N(1) atoms. The Mn(1)-N(2) bond length is 1.95 Å. There is one shorter (1.86 Å) and one longer (1.93 Å) Mn(1)-N(1) bond length. In the second Mn site, Mn(2) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form distorted edge-sharing MnN4 trigonal pyramids. Both Mn(2)-N(1) bond lengths are 1.92 Å. There is one shorter (2.07 Å) and one longer (2.20 Å) Mn(2)-N(2) bond length. There are two inequivalent N sites. In the first N site, N(1) is bonded to one Sr(2), two equivalent Sr(1), one Mn(2), and two equivalent Mn(1) atoms to form a mixture of distorted edge and corner-sharing NSr3Mn3 octahedra. The corner-sharing octahedral tilt angles range from 0-86°. In the second N site, N(2) is bonded in a distorted rectangular see-saw-like geometry to two equivalent Mn(1) and two equivalent Mn(2) atoms.
