Keep the dilute solution for crystallization

Hi Mr. Abanoub M. Abdallah
There is the only best way to get a single crystal of org or metal complex is TRY UNTIL YOU GET IT. But there are some tips: Make sure that your complex is pure, Keep dilute solution for crystallization, maintain constant room temperature, probably 20 degree C is good, Make sure that there is no vibration around crystallization place...... From my experience, Crystallization techniques for metal complex is Slow evaporation and Vapour diffusion method. If your complex soluble in wayer, better use water as solvent or mixture of solvents like MeCN-H2O or acetone-H2O
All the best

try T type pipes.put the compound at the bottom of the pipe and fill it with a bad solvent then put it in oil bath in a manner that the side part is placed on the oil.the crystalls will grow in the side hand (that is cold)

Prof. Dr. Joseph S Merola, thank you very much for your helpful answer.
I'll take the above information into my consideration.

Dissolve complex in hot DMF and allow to cool in a freezer . The complex will separate in crystalline form.

I do not know if there is really a simpler way to get a single crystal of a metal complex.  You could determine the solubility of your metal complex and use any of the techniques given in the following web link to grow crystals: http://web.mit.edu/x-ray/cystallize.html

Abanoub, there is no single "best" way to produce a single crystal.  First, for what purpose?  X-ray diffraction requires a certain size but neutron diffraction requires a bigger one.  Other studies may require very large crystals.
What is your complex soluble in? Is it air sensitive?  Thermally sensitive?  Does it react with any solvents?  All of these things will suggest different methods.   If you Google "Guide to growing single crystals" you will find the link that Sudarsan gives above and many, many more.  Vapor diffusion, liquid diffusion, thermal gradient, etc etc.
