Ba Be P
BaBeP crystallizes in the trigonal R3m space group. Ba(1) is bonded to three equivalent Be(1) and four equivalent P(1) atoms to form a mixture of edge and corner-sharing BaBe3P4 hexagonal pyramids. All Ba(1)-Be(1) bond lengths are 2.69 Å. There are three shorter (2.76 Å) and one longer (3.11 Å) Ba(1)-P(1) bond length. Be(1) is bonded in a single-bond geometry to three equivalent Ba(1) and one P(1) atom. The Be(1)-P(1) bond length is 1.01 Å. P(1) is bonded in a single-bond geometry to four equivalent Ba(1) and one Be(1) atom.
