چکیده    Acetylenic amine (n,n-bis propargy piperazine) were synthesized and diagnosed in spectroscopic method (uv-visibl and ir) and (c.h.n) analysis . preparing and studying new complexes by using ligand that from acetylenic amine which using this purpose at the first time with metal chlorides(mo +3 ,cr+5 ,w+6 ,fe+3 ). studying of complexes by using suitable methods have been diagnosed in uv-visible, ir, magnetic susceptibility , atomic absorption ,electric conductivity measurement and molar ratio, all result obtained from different techniques above which were found that their corresponding with the proposed structures for the prepared complexes . complexes appeared liquid crystal properties therefore they have been studied careful (δh, δs) of liquid crystal stages for both changes calculated which were found that their corresponding with the data in literature.
