Materials Data on Hf4AgPd by Materials Project

Hf2PdAgHf2 crystallizes in the tetragonal P4/mmm space group. The structure is two-dimensional and consists of one AgHf2 sheet oriented in the (0, 0, 1) direction and one Hf2Pd sheet oriented in the (0, 0, 1) direction. In the AgHf2 sheet, Hf is bonded in a 12-coordinate geometry to four equivalent Ag atoms. All Hf–Ag bond lengths are 3.02 Å. Ag is bonded in a distorted body-centered cubic geometry to eight equivalent Hf atoms. In the Hf2Pd sheet, Hf is bonded in a 4-coordinate geometry to four equivalent Pd atoms. All Hf–Pd bond lengths are 2.90 Å. Pd is bonded in a body-centered cubic geometry to eight equivalent Hf atoms.
