I am Working on developing Schiffs Base - Transition metal Complexes Having -OH Group at Terminal Position leading to the formation of Hydrogen bonding ! However I I unable to get the crystal Structure for the same !! Would anyone give me some suggestions Please ? Although I have tried almost all the solvents like MeOH, EtOH, Acetonitrile , etc
Dear Naseer, many thanks for sharing this very interesting chemical problem with the RG community. My general advice would be to try a different crystallization technique such as the vapor diffusion technique. Depending on the solubility of your compound you can prepare e.g. a solution of the complex in acetonitrile and put the solution in a small vial. Then place the vial in a larger closed glass container in which you put some diethyl ether. Over a few days the diethyl ether will diffuse into the solution and, if you are lucky, crystals will form at the interface layer. Of course this is just one of the different possible methods. For a good overview of different crystallization techniques please find attached three very useful manuals. Good luck with your work and best wishes, Frank Edelmann
Did you try mixture of solvents? Most of the time single solvent may not yield the crystal.
@sengottuvelan Balasubramanian , Yes I I tried few like DCM : MeoH , CHCl3:MeOH etc Etc
