We report magnetotransport measurements in a wide quantum well as the electron charge distribution is tuned from a single-layer through an interacting bilayer configuration to weakly coupled parallel layers. The system exhibits a remarkably rich set of correlated bilayer states including unique fractional quantum Hall states at even-denominator fillings and insulating phases which are consistent with pinned, bilayer Wigner crystal states.
