Materials Data on ReNCl4 by Materials Project
ReNCl4 crystallizes in the tetragonal I4 space group. The structure is one-dimensional and consists of two ReNCl4 ribbons oriented in the (0, 0, 1) direction. Re7+ is bonded to two equivalent N3- and four equivalent Cl1- atoms to form distorted corner-sharing ReN2Cl4 octahedra. The corner-sharing octahedral tilt angles are 0°. There are one shorter (1.69 Å) and one longer (2.42 Å) Re–N bond lengths. All Re–Cl bond lengths are 2.31 Å. N3- is bonded in a distorted linear geometry to two equivalent Re7+ atoms. Cl1- is bonded in a single-bond geometry to one Re7+ atom.
