Materials Data on RbSi2H18C6N by Materials Project
RbSi2C6NH18 crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of two RbSi2C6NH18 clusters. Rb1+ is bonded in a 2-coordinate geometry to two equivalent N3- atoms. There are one shorter (2.92 Å) and one longer (3.01 Å) Rb–N bond lengths. There are two inequivalent Si4+ sites. In the first Si4+ site, Si4+ is bonded to three C4- and one N3- atom to form corner-sharing SiC3N tetrahedra. There are a spread of Si–C bond distances ranging from 1.90–1.92 Å. The Si–N bond length is 1.69 Å. In the second Si4+ site, Si4+ is bonded to three C4- and one N3- atom to form corner-sharing SiC3N tetrahedra. There are a spread of Si–C bond distances ranging from 1.90–1.92 Å. The Si–N bond length is 1.70 Å. There are six inequivalent C4- sites. In the first C4- site, C4- is bonded to one Si4+ and three H1+ atoms to form corner-sharing CSiH3 tetrahedra. All C–H bond lengths are 1.10 Å.
