A new fluoride borate crystal, CdZn{sub 2}KB{sub 2}O{sub 6}F, has been synthesized by flux-supported solid-state reaction. The crystal structure has been determined by single-crystal X-ray diffraction. It crystallizes in the trigonal space group P3-barc1 with a=5.0381(6) A, b=5.0381(6) A, c=15.1550(19) A, alpha=90.00{sup o}, beta=90.00{sup o}, gamma=120.00{sup o}, Z=2. The crystal represents a new structure type in which ZnBO{sub 3} layers are connected through bridging fluorine and cadmium atoms alternately along the c-axis. K{sup +} cations are filled in the intralayer open channels to balance charge. IR and Raman spectra further confirm the crystal structure. Photoluminescent measurement reveals that CdZn{sub 2}KB{sub 2}O{sub 6}F exhibits blue fluorescence at room temperature in the solid-state. - Graphical abstract: Preparation, structure and fluorescence property of a new fluoride borate crystal, CdZn{sub 2}KB{sub 2}O{sub 6}F are descripted. The crystal represents a new structure type in which ZnBO{sub 3} layers are connected through bridging fluorine and cadmium atoms alternately to form a 3D open framework.
