TaSi2C6PH18(NCl3)2 crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of two TaSi2C6PH18(NCl3)2 clusters. Ta5+ is bonded in a 6-coordinate geometry to one N3- and five Cl1- atoms. The Ta–N bond length is 1.86 Å. There are a spread of Ta–Cl bond distances ranging from 2.34–2.80 Å. There are two inequivalent Si4+ sites. In the first Si4+ site, Si4+ is bonded to three C4- and one N3- atom to form SiC3N tetrahedra that share a cornercorner with one SiC3N tetrahedra and a cornercorner with one PN2Cl2 tetrahedra.

In the sixth 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. P5+ is bonded to two N3- and two Cl1- atoms to form PN2Cl2 tetrahedra that share corners with two SiC3N tetrahedra. There is one shorter (1.58 Å) and one longer (1.62 Å) P–N bond length. Both P–Cl bond lengths are 2.03 Å. There are two inequivalent N3- sites. In the first N3- site, N3- is bonded in a trigonal planar geometry to two Si4+ and one P5+ atom. In the second N3- site, N3- is bonded in a bent 150 degrees geometry to one Ta5+ and one P5+ atom. There are eighteen inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one C4- atom. In the second H1+ site, H1+ is bonded in a single-bond geometry to one C4- atom. In the third H1+ site, H1+ is bonded in a single-bond geometry to one C4- atom. In the fourth H1+ site, H1+ is bonded in a single-bond geometry to one C4- atom. In the fifth H1+ site, H1+ is bonded in a single-bond geometry to one C4- atom. In the sixth H1+ site, H1+ is bonded in a single-bond geometry to one C4- atom. In the seventh H1+ site, H1+ is bonded in a single-bond geometry to one C4- atom. In the eighth H1+ site, H1+ is bonded in a single-bond geometry to one C4- atom. In the ninth H1+ site, H1+ is bonded in a single-bond geometry to one C4- atom. In the tenth H1+ site, H1+ is bonded in a single-bond geometry to one C4- atom. In the eleventh H1+ site, H1+ is bonded in a single-bond geometry to one C4- atom. In the twelfth H1+ site, H1+ is bonded in a single-bond geometry to one C4- atom. In the thirteenth H1+ site, H1+ is bonded in a single-bond geometry to one C4- atom. In the fourteenth H1+ site, H1+ is bonded in a single-bond geometry to one C4- atom.
