Description
Summary:Colorless transparent single crystals of trilanthanum hexasilicon undecanitrogen, La3Si6N11, were prepared at 0.85 MPa of N2 and 2273 K. The title compound is isotypic with Sm3Si6N11. Silicon-centered nitrogen tetrahedra form a three-dimensional network structure by sharing their corners. Layers of one type of SiN4 tetrahedra and slabs composed of the two different La3+ cations and the other type of SiN4 tetrahedra are alternately stacked along the c axis of the tetragonal unit cell. The site symmetries of the two La3+ cations are are ..m and 4.., respectively.
