We have reinvestigated the {beta} decay of the three isomers of {sup 116}Ag at the Holifield Radioactive Ion Beam Facility (HRIBF). Through the use of half-life information, we have been able to construct individual decay schemes for each isomer and correct what was a puzzling inconsistency with the published data, namely the {beta} feeding of 2{sup +} states by a 5{sup +} isomer. Our results indicate that the feeding of these levels arises from a 3{sup +} isomer in {sup 116}Ag. A total of 271{gamma}-ray transitions (159 new) were assigned to 148 levels (94 new) from the {beta} decay of {sup 116}Ag{sup m1,m2,gs}. Significant deviations are observed from IBM-2 calculations for the decay of the 0{sup +} and 2{sup +} members of the previously assigned three-phonon quintuplet. Candidate states for the quadrupole-octupole quintuplet states and {pi}g{sub 9/2}-{pi}p{sub 1/2}, {pi}g{sub 9/2}-{pi}p{sub 3/2}, {nu}h{sub 11/2}-{nu}s{sub 1/2}, {nu}h{sub 11/2}-{nu}d{sub 3/2}, and {nu}h{sub 11/2}-{nu}d{sub 5/2} broken-pair states are assigned.
