Sr2VN2 crystallizes in the orthorhombic Cmce space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a 5-coordinate geometry to two equivalent N(2) and three equivalent N(1) atoms. In the second Sr site, Sr(2) is bonded to two equivalent N(1) and three equivalent N(2) atoms to form a mixture of distorted corner and edge-sharing SrN5 square pyramids. V(1) is bonded in a bent 120 degrees geometry to one N(1) and one N(2) atom. There are two inequivalent N sites. In the first N site, N(1) is bonded to two equivalent Sr(2), three equivalent Sr(1), and one V(1) atom to form a mixture of distorted corner and edge-sharing NSr5V octahedra. The corner-sharing octahedral tilt angles are 21°. In the second N site, N(2) is bonded in a 6-coordinate geometry to two equivalent Sr(1), three equivalent Sr(2), and one V(1) atom.

In the first Sr site, Sr(1) is bonded in a 5-coordinate geometry to two equivalent N(2) and three equivalent N(1) atoms. There is one shorter (2.60 Å) and one longer (3.24 Å) Sr(1)-N(2) bond length. There are two shorter (2.69 Å) and one longer (2.78 Å) Sr(1)-N(1) bond length. In the second Sr site, Sr(2) is bonded to two equivalent N(1) and three equivalent N(2) atoms to form a mixture of distorted corner and edge-sharing SrN5 square pyramids. There is one shorter (2.67 Å) and one longer (2.89 Å) Sr(2)-N(1) bond length. There are two shorter (2.66 Å) and one longer (2.75 Å) Sr(2)-N(2) bond length.
