States in doubly odd {sup 216}Fr have been studied using in-beam {alpha}, {gamma}, and {ital e}{sup {minus}} spectroscopy techniques through the {sup 208}Pb({sup 11}B3{ital n}) fusion-evaporation reaction. {sup 216}Fr shows a band structure with interleaved states of alternating parities connected by enhanced {ital B}({ital E}1) transitions. It represents the lowest-mass corner of the region ({ital Z}{ge}87,{ital N}{ge}129) in which this phenomenon is observed.
