Materials Data on Pa3H by Materials Project
Pa3H crystallizes in the hexagonal P6_3/mmc space group. The structure is one-dimensional and consists of two Pa3H ribbons oriented in the (0, 0, 1) direction. Pa is bonded in a distorted L-shaped geometry to two equivalent H atoms. Both Pa–H bond lengths are 2.58 Å. H is bonded in a 6-coordinate geometry to six equivalent Pa atoms.
