I prepared a certain inorganic structure but it don"t have XRD card to identify it. How can I identify the new structure to be sure that it is formed ??? I need a non-destructive technique ???
Dear Eman,
Do you have a XRD diffractometer? Because if you are only missing the card I know there are free databases (and also free-trials software) to identify it. Regarding other techniques, to the best of my knowledge the only way you have to know the structure is through SAED (selected area diffraction) or, If you have one, HR-TEM.
XRD is universal technique to identify solids. What are your starting materials? What is the temperature? What is the expected product after firing? What is your search-match software? What kind of database that you use ICDD, ICSD or COD. You have to give more details to let experts help you.

To be honest X-ray single crystallography considers as finger print for any complex,. But if you do not have crystals for it, there are different techniques are used together to be certain about its formation and its structure such as H1-NMR, C13-NMR if they are diamagnetic, low and high mass, CHN, IR and UV-Visible.
Well, in order to suggest techniques, we need to know something more about the material. Does it have solubility in any solvents? That determines whether or not NMR spectroscopy might be of use. Does it have any particular functional groups? Then IR spectroscopy might help. Mass spectrometry is not non-destructive, but it uses so little material. If you have a mass spec for which you have an appropriate direct inlet, that might work well. As others have already stated, you don't need a "card" to identify your material, you should be able to find a comparison either in a free database or in the literature.
