Abstract: Single crystals of solid solutions (NH$_4$)$_{2-x}$Rb$_x$MoO$_2$F$_4$ (including individual complex Rb$_2$MoO$_2$F$_4$) have been grown and studied using polarization-optical methods. The birefringence $\Delta n(T)$ has been measured in the temperature range of 100–400 K. The complete $(T-x)$ phase diagram has been constructed.
