The low-lying structure of Sn112 has been studied by use of the (n,n'γ) reaction. Excitation functions and angular distributions of γ rays have been used to characterize the decays of the excited levels, and level lifetimes have been measured with the Doppler-shift attenuation method. A γ-γ coincidence experiment has also been performed to confirm γ-ray placements. Low-lying 1-, 2(-),3-, and 5- states are suggested as members of a heterogeneous quadrupole-octupole quintuplet. Their excitation energies and decay properties are consistent with a structure formed by the coupling of the lowest quadrupole 21+ and octupole 31- excitations.
