Sr2PbN2 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. Pb(1) is bonded in a water-like 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 Pb(1) atom to form a mixture of corner and edge-sharing NSr5Pb octahedra. The corner-sharing octahedral tilt angles range from 2-55°. In the second N site, N(2) is bonded to two equivalent Sr(1), three equivalent Sr(2), and one Pb(1) atom to form a mixture of corner and edge-sharing NSr5Pb octahedra. The corner-sharing octahedral tilt angles range from 2-55°.

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 (2.62 Å) and one longer (2.75 Å) Sr(1)-N(2) bond length. There are two shorter (2.79 Å) and one longer (2.87 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.
