Abstract

Zr3Al3C5 crystallizes in the hexagonal P6_3/mmc space group. The structure is two-dimensional and consists of two AlC sheets oriented in the (0, 0, 1) direction and two Zr3(AlC2)2 sheets oriented in the (0, 0, 1) direction. In each AlC sheet, Al3+ is bonded in a trigonal planar geometry to three equivalent C4- atoms. All Al–C bond lengths are 1.91 Å. C4- is bonded in a trigonal planar geometry to three equivalent Al3+ atoms. In each Zr3(AlC2)2 sheet, there are two inequivalent Zr+3.67+ sites. In the first Zr+3.67+ site, Zr+3.67+ is bonded to six equivalent C4- atoms to form a mixture of corner and edge-sharing ZrC6 octahedra. The corner-sharing octahedral tilt angles are 3°. All Zr–C bond lengths are 2.37 Å. In the second Zr+3.67+ site, Zr+3.67+ is bonded to six C4- atoms to form a mixture of corner and edge-sharing ZrC6 octahedra. The corner-sharing octahedral tilt angles are 3°. There are three shorter (2.29 Å) and three longer (2.59 Å) Zr–C bond lengths. Al3+ is bonded in a trigonal non-coplanar geometry to three equivalent C4- atoms. All Al–C bond lengths are 2.09 Å. There are two inequivalent C4- sites. In the first C4- site, C4- is bonded in a 3-coordinatemore »« less
