I have got str soln of the attached polymorph thro' reflex module of MS done and it is successfully predicted too w.r.t its lattice parameters. It is exactly matching with already known crystal str. i.e dalgon (reported in ccdc) but the str has been totally tilted seems to be cis- isomer but parametrs are same as trans-isomer. 

How wud we predict the cis-isomer? I tried to draw str of cis-isomer in MS and predicted  the conformers but in vain. No match was found. 

How should I correlate the str. i.e exerimental solved str. and predicted str now?

 I am attaching the powder solved  crystal str.
