Cyanide-bridged one-dimensional bimetallic complexes based on a tridentate copper(II) building block: synthesis, crystal structures and magnetic properties
The reactions of [M III (CN) 6 ] 3− (M = Cr or Co) with Cu II complexes of a tridentate schiff base [Cu(aemp)Cl] or [Cu(aemp)Ac] 2 (Haemp = 2-[(2-amino-ethylimino)-methyl]-phenol) give rise to 1D cyanide-bridged bimetallic coordination polymers [Cu 4 (aemp) 4 (H 2 O) 2 ][Cr(CN) 6 ]Cl ( 1 ) and [Cu 3...
