Syntheses, crystal structures and properties of copper(II) complexes of 1-amidinoisourea and biguanide nitrates

Copper(II) complexes of amidinoisourea and biguanidine derivatives [Cu{NH2(CNH)NH(CNH)Y}Y]2 (NO3)2, where Y = OR, NHR or NRR (R = Me, Et, Pr, iPr, allyl, Bu, iBu, Bz, Cp, Cy) suitable for inflating gas generating systems were synthesized and characterized by elemental analysis, mass spectrometry and FTIR spectroscopy. The structures of three complexes were determined by X-ray diffraction. Thermal behavior was studied by differential thermal analysis and the decomposition temperatures indicated good thermal stability. Enthalpies of formation of the complexes are influenced by the substituent Y.
