Antimony-doped K{sub 1-x}Ti{sub 1-x}Sb{sub x}OPO{sub 4}, x=0.23, crystals have been prepared by spontaneous nucleation from the flux in the quaternary system K{sub 2}O-TiO{sub 2}-P{sub 2}O{sub 5}-Sb{sub 2}O{sub 5}. Crystal structure observation with TEM method reveals the presence of superstructure ordering. Core level electronic parameters have been studied by X-ray photoelectron spectroscopy. Strong effect of Sb doping has been detected for inner shells of Ti{sup 4+} ions. Prominent decreasing of the binding energy difference {delta}(O 1s-Ti 2p{sub 3/2}) correlates with the shortening of mean oxide bond length L(Ti-O) at x=0.23 that suggests increased ionicity of Ti-O bonds in K{sub 1-x}Ti{sub 1-x}Sb{sub x}OPO{sub 4} solid solutions.
