Abstract: The crystal structure of the title heteronuclear complex, [PrZn₂(C₄H₅O₂)₆(NO₃)(C₁₀H₈N₂)₂], is made up of discrete molecules of a trinuclear Zn-Pr-Zn complex with the central Pr atom bridged by three bidentate [alpha] -methylacrylate groups to each of the two Zn atoms. In the complex, the Pr atom is coordinated by six O atoms from the bridging methylacrylate groups and by two O atoms from a bidentate chelate nitrato group in a distorted square antiprismatic configuration. Each Zn ion is five-coordinated by three O atoms from three bridging methylacrylate groups and by two N atoms from a bipyridine in a distorted trigonal-bipyramidal configuration.
