The structure described by Ba4W(N2Cl)2 crystallizes in the monoclinic P2_1/m space group. There are four inequivalent Ba sites.

The corner-sharing octahedral tilt angles range from 53-71°. In the second Ba site, Ba(2) is bonded in a 8-coordinate geometry to two equivalent N(1), four equivalent N(2), one Cl(1), and one Cl(2) atom.

The corner-sharing octahedral tilt angles range from 53-56°. In the third N site, N(3) is bonded in a 5-coordinate geometry to one Ba(1), one Ba(4), two equivalent Ba(3), and one W(1) atom. There are two inequivalent Cl sites.
