摘要: Abstract Five compounds of the Cs2BX4 family with B = Zn, Co, Cu and X Cl, Br were grown studied. They belong to Pnma space group 4 formula units per cell. From full determination structure it appears that ZnX4 tetrahedra are almost regular while CuX4 strongly distorted. This seems be due a strong Jahn-Teller effect induced by ions. remark is extended other general A2BX4.
