Ca2MgWO6 from neutron and X-ray powder data.
The room-temperature structure of the B-site-ordered complex perovskite dicalcium magnesium tungstate, Ca(2)MgWO(6), has been determined by simultaneous Rietveld refinement of neutron and X-ray powder diffraction patterns. Ca(2)MgWO(6) is characterized by B-site ordering and an a(-)a(-)c(+)-type BO(6) octahedral tilt mechanism.
