Materials Data on PC2N3Cl4 by Materials Project
C2PN3Cl4 is beta Sn-like structured and crystallizes in the orthorhombic Cmcm space group. The structure is zero-dimensional and consists of four C2PN3Cl4 clusters. C4+ is bonded in a trigonal planar geometry to two N3- and one Cl1- atom. There is one shorter (1.32 Å) and one longer (1.34 Å) C–N bond length. The C–Cl bond length is 1.74 Å. P5+ is bonded in a tetrahedral geometry to two equivalent N3- and two equivalent Cl1- atoms. Both P–N bond lengths are 1.62 Å. Both P–Cl bond lengths are 1.99 Å. There are two inequivalent N3- sites. In the first N3- site, N3- is bonded in a bent 120 degrees geometry to two equivalent C4+ atoms. In the second N3- site, N3- is bonded in a bent 120 degrees geometry to one C4+ and one P5+ atom. There are two inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a single-bond geometry to one C4+ atom. In the second Cl1- site, Cl1- is bonded in a single-bond geometry to one P5+ atom.
