51V NMR, DTA, and thermogravimetric analysis are used to study the thermal behavior of a manganese-nickel pyrovanadate complex Mn2–2xNi2xV2O7. It is shown that the nature of 51V hyperfine interactions in manganese pyrovanadate and solid solutions based on its polymorphic modifications is specified by the structurally activated oxygen exchange with the gaseous phase.
