The material described by BC2PH9 is Indium-like structured and crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of two BC2PH9 clusters. B(1) is bonded to one P(1), one H(3), one H(4), and one H(7) atom to form distorted BPH3 tetrahedra that share  a cornercorner with one C(1)PH3 tetrahedra and  a cornercorner with one C(2)PH3 tetrahedra. There are two inequivalent C sites. In the first C site, C(1) is bonded to one P(1), one H(1), one H(6), and one H(9) atom to form distorted CPH3 tetrahedra that share  a cornercorner with one B(1)PH3 tetrahedra and  a cornercorner with one C(2)PH3 tetrahedra. In the second C site, C(2) is bonded to one P(1), one H(2), one H(5), and one H(8) atom to form distorted CPH3 tetrahedra that share  a cornercorner with one B(1)PH3 tetrahedra and  a cornercorner with one C(1)PH3 tetrahedra. P(1) is bonded in a 4-coordinate geometry to one B(1), one C(1), one C(2), and one P(1) atom. There are nine inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one C(1) atom. In the second H site, H(2) is bonded in a single-bond geometry to one C(2) atom. In the third H site, H(3) is bonded in a single-bond geometry to one B(1) atom. In the fourth H site, H(4) is bonded in a single-bond geometry to one B(1) atom. In the fifth H site, H(5) is bonded in a single-bond geometry to one C(2) atom. In the sixth H site, H(6) is bonded in a single-bond geometry to one C(1) atom. In the seventh H site, H(7) is bonded in a single-bond geometry to one B(1) atom. In the eighth H site, H(8) is bonded in a single-bond geometry to one C(2) atom. In the ninth H site, H(9) is bonded in a single-bond geometry to one C(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
