Li2CuAs crystallizes in the hexagonal P6_3/mmc space group. Li(1) is bonded in a 7-coordinate geometry to three equivalent Cu(1) and four equivalent As(1) atoms. Cu(1) is bonded in a distorted q6 geometry to six equivalent Li(1) and three equivalent As(1) atoms. As(1) is bonded in a 11-coordinate geometry to eight equivalent Li(1) and three equivalent Cu(1) atoms.
Li2CuAs crystallizes in the hexagonal P6_3/mmc space group. Li(1) is bonded in a 7-coordinate geometry to three equivalent Cu(1) and four equivalent As(1) atoms. All Li(1)-Cu(1) bond lengths are 2.72 Å. There is one shorter (2.65 Å) and three longer (2.72 Å) Li(1)-As(1) bond lengths. Cu(1) is bonded in a distorted q6 geometry to six equivalent Li(1) and three equivalent As(1) atoms. All Cu(1)-As(1) bond lengths are 2.39 Å. As(1) is bonded in a 11-coordinate geometry to eight equivalent Li(1) and three equivalent Cu(1) atoms.
