Abstract: | Single crystals of a new rubdidium beryllium borate, RbBe4(BO3)3, have been obtained by spontaneous nucleation from a high‐temperature melt. This new orthorhombic (Pnma) structure type contains [Be2BO4]− rings, made of two BeO4 tetrahedra and one BO3 triangle, which constitute the basic structural units. The m plane runs through the B and one of the O atoms and intersects the ring. These rings form chains in the a direction, which are connected in the b and c directions to form zeolite‐type cages in which the Rb+ cations are located, at sites of m symmetry. |
