AbstractA new pyroborate Sr2ScLiB4O10 has been synthesized and structurally characterized by single-crystal X-ray diffraction methods. It crystallizes with four formula units in a cell of dimensions a=12.543(1) Å, b=5.2201(6) Å, c=13.635(2) Å, and β=116.69(1)°. The structure is a new type having layers of pyroborate groups with the associated cations residing in interlayer interstices. The Sr atoms occupy sites in sevenfold coordination and the Sc atom occupies a distorted octahedron. Five-coordinate Li atoms reside in oblong tunnels extending along the direction [0 1 0].
