title: Materials Data on AlGe2P(H3C)8 by Materials Project

description: AlGe2P(CH3)8 crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of one AlGe2P(CH3)8 cluster. Al3+ is bonded to two C4- and two equivalent P3- atoms to form AlP2C2 tetrahedra that share corners with four GePC3 tetrahedra and an edgeedge with one AlP2C2 tetrahedra. There is one shorter (1.98 Å) and one longer (1.99 Å) Al–C bond length. Both Al–P bond lengths are 2.47 Å. There are two inequivalent Ge4+ sites. In the first Ge4+ site, Ge4+ is bonded to three C4- and one P3- atom to form GePC3 tetrahedra that share a cornercorner with one GePC3 tetrahedra and corners with two equivalent AlP2C2 tetrahedra. There is one shorter (1.96 Å) and two longer (1.97 Å) Ge–C bond length. The Ge–P bond length is 2.36 Å. In the second Ge4+ site, Ge4+ is bonded to three C4- and one P3- atom to form GePC3 tetrahedra that share a cornercorner with one GePC3 tetrahedra and corners with two equivalent AlP2C2 tetrahedra. All Ge–C bond lengths are 1.97 Å. The Ge–P bond length is 2.36 Å. There are eight inequivalent C4- sites. In the first C4- site, C4- is bonded to one Ge4+ and three H1+ atoms to form distorted CGeH3 tetrahedra that share a cornercorner with one PAl2Ge2 tetrahedra and corners with two CGeH3 tetrahedra.

In the sixth C4- site, C4- is bonded to one Ge4+ and three H1+ atoms to form distorted CGeH3 tetrahedra that share a cornercorner with one PAl2Ge2 tetrahedra and corners with two CGeH3 tetrahedra. All C–H bond lengths are 1.10 Å. In the seventh C4- site, C4- is bonded to one Al3+ and three H1+ atoms to form CAlH3 tetrahedra that share a cornercorner with one CAlH3 tetrahedra and corners with two equivalent PAl2Ge2 tetrahedra. All C–H bond lengths are 1.10 Å. In the eighth C4- site, C4- is bonded to one Ge4+ and three H1+ atoms to form distorted CGeH3 tetrahedra that share a cornercorner with one PAl2Ge2 tetrahedra and corners with two CGeH3 tetrahedra. All C–H bond lengths are 1.10 Å. P3- is bonded to two equivalent Al3+ and two Ge4+ atoms to form PAl2Ge2 tetrahedra that share corners with ten CGeH3 tetrahedra and an edgeedge with one PAl2Ge2 tetrahedra. There are twenty-four 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.
