Tetrakis(μ3-9-oxa-10-boraanthracen-10-olato)tetrakis[(diethyl ether)lithium]
The title compound, [Li4O4(C12H8BO)4(C4H10O)4], features a Li4O4 cube. Each Li atom in the cube is additionally coordinated by a diethyl ether molecule and each O atom in the cube carries a 9-oxa-10-boraanthracene residue. The crystal studied was a non-merohedral twin [twin law (-1 0 0 / 0 0 1 / 0 1 0); the contribution of the major twin component refined to 0.553 (3)] emulating apparent tetragonal symmetry, whereas the actual crystal system is just orthorhombic
