Materials Data on Rb2Pb2N by Materials Project
Rb2Pb2N crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are four inequivalent Rb sites. In the first Rb site, Rb is bonded in a distorted single-bond geometry to two Pb and one N atom. There are one shorter (3.93 Å) and one longer (4.29 Å) Rb–Pb bond lengths. The Rb–N bond length is 2.79 Å. In the second Rb site, Rb is bonded in a 2-coordinate geometry to two equivalent Pb and two N atoms. There are one shorter (3.59 Å) and one longer (4.28 Å) Rb–Pb bond lengths. There are one shorter (3.11 Å) and one longer (3.12 Å) Rb–N bond lengths. In the third Rb site, Rb is bonded in a 1-coordinate geometry to four Pb and two equivalent N atoms. There are a spread of Rb–Pb bond distances ranging from 3.69–4.03 Å. There are one shorter (2.81 Å) and one longer (3.36 Å) Rb–N bond lengths. In the fourth Rb site, Rb is bonded in a distorted water-like geometry to two equivalent N atoms. There are one shorter (2.87 Å) and one longer (2.99 Å) Rb–N bond lengths. There are four inequivalent Pb sites. In the first Pb site, Pb is bonded in a 5-coordinate geometry to five Rb and three Pb atoms. There are a spread of Pb–Pb bond distances ranging from 2.84–3.53 Å. In the second Pb site, Pb is bonded in a single-bond geometry to one Pb and one N atom. The Pb–N bond length is 2.04 Å. In the third Pb site, Pb is bonded in a 5-coordinate geometry to three Rb and two Pb atoms. The Pb–Pb bond length is 3.46 Å. In the fourth Pb site, Pb is bonded in a distorted single-bond geometry to two Pb and one N atom. The Pb–N bond length is 2.06 Å. There are two inequivalent N sites. In the first N site, N is bonded to four Rb and one Pb atom to form distorted edge-sharing NRb4Pb trigonal bipyramids. In the second N site, N is bonded in a see-saw-like geometry to three Rb and one Pb atom.
