The structure of trihafnium diphosphide, Hf3P2, has been redetermined by single-crystal analysis. Hf3P2 crystallizes in the orthorhombic space group Pnma (No. 62), with a = 10.128 (2), b = 3.5707 (6), c = 9.868 (2) Å, V = 356.87 (12) Å3, in the anti-Sb2S3 structure type. The P atoms are situated in singly capped and bicapped trigonal Hf prisms. In contrast to the structure of Zr14P9, no centered Hf cubes as observed in the bcc packing occur in the structure of Hf3P2.
