The compound described by NdCl4N2Cl crystallizes in the orthorhombic Pnma space group. The structure consists of four N2Cl clusters inside a NdCl4 framework. In each N2Cl cluster, N(1) is bonded in a single-bond geometry to one Cl(3) atom. Cl(3) is bonded in a bent 120 degrees geometry to two equivalent N(1) atoms. In the NdCl4 framework, Nd(1) is bonded to one Cl(1), two equivalent Cl(4), and four equivalent Cl(2) atoms to form a mixture of distorted edge and corner-sharing NdCl7 pentagonal bipyramids. There are three inequivalent Cl sites. In the first Cl site, Cl(2) is bonded in a water-like geometry to two equivalent Nd(1) atoms. In the second Cl site, Cl(1) is bonded in a single-bond geometry to one Nd(1) atom. In the third Cl site, Cl(4) is bonded in a distorted linear geometry to two equivalent Nd(1) atoms. is represented by the CIF file [CIF]
