Hi

I have powder solved one pxrd data(expt.) of a crystal str. and then tried to match it with the predicted ones as follows-

Lattice parameters-

Predicted best match-

a=26.607247, b=7.019383, c=11.513122 & beta=97.76649, crys. density= 1.42316

powder solve crys. str solution-

a= 26.629629, b=9.065169, c=12.019799 & beta=99.30071, cyrs. density= 1.05890

Space gp. = C2/c (both strs.)

But I found that their H- bonding is not matching. So can I consider it as  best match or else what should Ido? I tried to powder solve with other  space groups too but didnt get get to fully match parameters with predicted one. Then what conclusion should i draw?
