RbMoPO with large birefringence mainly induced by highly distorted [MoO] in uncommon [MoPO] layers
The introduction of d 0 transition metal Mo 6+ cations into a phosphate generates a new acentric molybdophosphate, RbMo 2 P 3 O 14 . It shows uncommon [Mo 2 P 3 O 14 ] ∞ layers composed of isolated [MoO 6 ] octahedra and [P 3 O 10 ] groups. To the best of our acknowledge, it exhibits the largest bir...

] groups. To the best of our acknowledge, it exhibits the largest birefringence (a calculated value of 0.166 at 546 nm) among reported molybdophosphates. In addition, it also possesses a shorter UV cut-off edge (about 250 nm) than other molybdates and molybdophosphates, indicating that it can be used as a birefringent crystal in the UV optical region. First-principles electronic structure analysis suggests that the large birefringence mainly originates from highly distorted [MoO

].
