A new trirutile MTa2O6 was synthesized by thermal decomposition of a freeze dried Cu- Ta-oxalate precursor. Its formation takes place preferentially starting from Cu-rich precursor compositions. Above 1000°C decomposition leads to the already known perovskite like structure with a composition Cu1.05Ta1.98O6 . The degree of the orthorhombic distortion of the perovskite unit cell depends on the conditions during the cooling process after perovskite formation.
