In the first N site, N(9) is bonded in a trigonal planar geometry to one Ti(4), one Ti(5), and one Ti(7) atom. In the second N site, N(10) is bonded in a distorted trigonal planar geometry to one Ti(4), one Ti(6), and one Ti(7) atom. In the third N site, N(1) is bonded in a 2-coordinate geometry to one Sr(1), one Ti(1), and one Ti(5) atom.

In the fifth N site, N(3) is bonded in a distorted trigonal planar geometry to one Ti(1), one Ti(2), and one Ti(6) atom. In the sixth N site, N(4) is bonded in a distorted trigonal planar geometry to one Sr(1), one Ti(2), and one Ti(3) atom. In the seventh N site, N(5) is bonded in a trigonal non-coplanar geometry to one Ti(3), one Ti(6), and one Ti(7) atom. In the eighth N site, N(6) is bonded in a trigonal planar geometry to one Ti(1), one Ti(2), and one Ti(7) atom.
