Complex long-range magnetic ordering in the Mn-bearing dugganite Pb3TeMn3P2O14

Two geometrically frustrated cationic substructures of the langasites and dugganites have profound effects on the magnetism of these compounds. In Pb3TeMn3P2O14, Mn2+ (S=5/2) isolated trinuclear units are shown in yellow, while the red distorted kagomé network is nonmagnetic.
