“…Our dataset contains no data for As 3+ , Se 4+ , Sb 3+ , Te 4+ Bi 3+ , or any relevant group 17 cations. Only one coordination polyhedron was recorded for Sn 2+ , in Li(Sn(NH 2 ) 3 ) (50467), 187 with three short bonds 2.128, 2.132 and 2.170 Å in length and a stereoactive lone pair occupying the 4 th apex of a tetrahedron. For period 6 ions, eight coordination polyhedra were recorded for Tl + and two for Pb 2+ ; in all cases, short bonds are concentrated in one hemisphere, away from the lone pair, while long bonds (if any) are present in the other.…”

“…Presumably, this paucity of data is due to the relatively nascent exploration of (functional) inorganic nitrides. Our dataset contains no data for As 3+ , Se 4+ , Sb 3+ , Te 4+ Bi 3+ , or any relevant group 17 cations Only one coordination polyhedron was recorded for Sn 2+ , in Li(Sn(NH2)3) (50467), 185 with three short bonds 2.128, 2.132 and 2.170 Å in length and a stereoactive lone pair occupying the 4 th apex of a tetrahedron.

The scarcity of nitrogen in Earth’s crust, combined with challenging synthesis, have made inorganic nitrides a relatively-unexplored class of compounds compared to their naturally-abundant oxide counterparts. To facilitate exploration of their compositional space via a priori modeling, and to help a posteriori structure verification not limited to inferring the oxidation state of redox-active cations, we derive a suite of bond-valence parameters and Lewis-acid strength values for 76 cations observed bonding to N3-, and further outline a baseline statistical knowledge of bond lengths for these compounds. We examine structural and electronic effects responsible for the functional properties and anomalous bonding behavior of inorganic nitrides, and identify promising venues for exploring uncharted compositional spaces beyond the reach of high-throughput computational methods. We find that many mechanisms of bond-length variation ubiquitous to oxide and oxysalt compounds (e.g., lone-pair stereoactivity, the Jahn-Teller and pseudo Jahn-Teller effects) are similarly pervasive in inorganic nitrides, and are occasionally observed to result in greater distortion magnitude than their oxide counterparts. We identify inorganic nitrides with multiply-bonded metal ions as a promising venue in heterogeneous catalysis, e.g. in the development of a post-Haber-Bosch process proceeding at milder reaction conditions, thus representing further opportunity in the thriving exploration of the functional properties of this emerging class of materials.
