RbNiC2N2Cl crystallizes in the tetragonal I4/mmm space group. Rb(1) is bonded in a square co-planar geometry to four equivalent Cl(1) atoms. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a square co-planar geometry to four equivalent C(1) atoms. In the second Ni site, Ni(2) is bonded in an octahedral geometry to four equivalent N(1) and two equivalent Cl(1) atoms. C(1) is bonded in a linear geometry to one Ni(1) and one N(1) atom. N(1) is bonded in a linear geometry to one Ni(2) and one C(1) atom. Cl(1) is bonded to four equivalent Rb(1) and one Ni(2) atom to form a mixture of distorted edge and corner-sharing ClRb4Ni square pyramids.
