We found a linear relationship between the metal–insulator transition (MIT) temperature and the A + ionic radius of the beta‐A 0.33 V 2 O 5 bronze family, leading our attention to beta‐K 0.33 V 2 O 5 which has been neglected for a long time. We have introduced a facile hydrothermal method to obtain the single‐crystalline beta‐K 0.33 V 2 O 5 nanorods. As expected, both the temperature‐dependence of the resistivity and magnetization demonstrated MITs at about 72 K for beta‐K 0.33 V 2 O 5 , thus matching well with the linear relationship described above. The beta‐K 0.33 V 2 O 5 was assigned as a new member of the beta‐A 0.33 V 2 O 5 bronze family for their similar crystal and electronic structures and their MIT property; this addition enriches the beta‐A 0.33 V 2 O 5 bronze family.
