Materials Data on Eu3S by Materials Project
Eu3S crystallizes in the hexagonal P6_3/mmc space group. The structure is one-dimensional and consists of two Eu3S ribbons oriented in the (0, 0, 1) direction. Eu is bonded in a distorted L-shaped geometry to two equivalent S atoms. Both Eu–S bond lengths are 2.95 Å. S is bonded to six equivalent Eu atoms to form distorted face-sharing SEu6 pentagonal pyramids.
