The atoms on the two phenyl rings and the dien chain are disordered
in two positions with 55/45 occupancies. Their temperature factors
(Ueq) were evened by using commands DELU&SIMU in the following
refinement.

The hydrogen atom of the -HCO3 group was located from difference
Fourier maps and refined isotropically. It was set to point to the
tertiary amine acceptor located on the dien chain and its hydrogen
bond length was constrained to 0.82 angstrom by using command DFIX.
