Materials Data on Te4Pt3 by Materials Project

Pt3Te4 crystallizes in the monoclinic C2/m space group. The structure is one-dimensional and consists of two Pt3Te4 ribbons oriented in the (0, 1, 0) direction. there are two inequivalent Pt+2.67+ sites. In the first Pt+2.67+ site, Pt+2.67+ is bonded in a T-shaped geometry to three Te2- atoms. There are two shorter (2.69 Å) and one longer (2.74 Å) Pt–Te bond lengths. In the second Pt+2.67+ site, Pt+2.67+ is bonded in a linear geometry to two equivalent Te2- atoms. Both Pt–Te bond lengths are 2.58 Å. There are two inequivalent Te2- sites. In the first Te2- site, Te2- is bonded in a 2-coordinate geometry to two equivalent Pt+2.67+ atoms. In the second Te2- site, Te2- is bonded in a 5-coordinate geometry to two Pt+2.67+ atoms.

Materials Data on Te4Pt3 by Materials Project

Pt3Te4 crystallizes in the monoclinic C2/m space group. The structure is two-dimensional and consists of two PtTe sheets oriented in the (0, 0, 1) direction and one PtTe2 sheet oriented in the (0, 0, 1) direction. In each PtTe sheet, Pt+2.67+ is bonded in a distorted trigonal non-coplanar geometry to three equivalent Te2- atoms. There are two shorter (2.63 Å) and one longer (2.64 Å) Pt–Te bond lengths. Te2- is bonded in a 3-coordinate geometry to three equivalent Pt+2.67+ atoms. In the PtTe2 sheet, Pt+2.67+ is bonded to six equivalent Te2- atoms to form edge-sharing PtTe6 octahedra. All Pt–Te bond lengths are 2.72 Å. Te2- is bonded in a 3-coordinate geometry to three equivalent Pt+2.67+ atoms.

In the first Te2- site, Te2- is bonded in a 6-coordinate geometry to two Pt+2.67+ atoms. In the second Te2- site, Te2- is bonded in a distorted bent 120 degrees geometry to two equivalent Pt+2.67+ atoms.
