Be Ge P P
BeGeP2 crystallizes in the monoclinic Cm space group. Be(1) is bonded in a 6-coordinate geometry to two equivalent Ge(1) and four equivalent P(1) atoms. There is one shorter (2.02 Å) and one longer (2.26 Å) Be(1)-Ge(1) bond length. There are two shorter (1.99 Å) and two longer (2.29 Å) Be(1)-P(1) bond lengths. Ge(1) is bonded in a 6-coordinate geometry to two equivalent Be(1) and four equivalent P(1) atoms. There are two shorter (2.46 Å) and two longer (2.49 Å) Ge(1)-P(1) bond lengths. P(1) is bonded in a 6-coordinate geometry to two equivalent Be(1), two equivalent Ge(1), and two equivalent P(1) atoms. Both P(1)-P(1) bond lengths are 2.48 Å.
