Solid-state transition metal chemistry with imidazol-2-yl-methyl[N-(n-butyl)amino]-diphenylphosphine oxide (2-izmape). Crystal structure of the [Cu(2-izmape)2](ClO4)2 complex

The perchlorate transition metal (Cu, Ni, Co) complexes with new class of aminophosphonate ligand derived from imidazole, i.e. the imidazol-2-yl-methyl[N-(n-butyl)amino]-diphenylphosphine oxide (2-izmape) ligand were prepared and studied spectroscopically and magnetically. In particular, the crystal structure of [Cu(2-izmape)2](ClO4)2 was determined by the X-ray diffraction method. The magnetic results suggest the possibility of weak ferromagnetic (Ni, Co) interaction between paramagnetic centers in crystal lattice. Copper centers are magnetically isolated.
