description: Si2C10NH25 is Modderite-derived structured and crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of two 1,3-bis(di-tert-butylsilyl)-2,2,4,4-tetramethylcyclobutanedisilazane molecules. there are two inequivalent Si4+ sites. In the first Si4+ site, Si4+ is bonded to two C3-, one N3-, and one H1+ atom to form corner-sharing SiHC2N tetrahedra. Both Si–C bond lengths are 1.94 Å. The Si–N bond length is 1.76 Å. The Si–H bond length is 1.51 Å. In the second Si4+ site, Si4+ is bonded to two C3- and two equivalent N3- atoms to form SiC2N2 tetrahedra that share corners with two equivalent SiHC2N tetrahedra and an edgeedge with one SiC2N2 tetrahedra. Both Si–C bond lengths are 1.88 Å. Both Si–N bond lengths are 1.77 Å. There are ten inequivalent C3- sites.
