Crystal structure and topological ferrimagnetic behavior of a new 2D metal-organic hybrid manganese complex [Mn3(N3)4(L)2(H2O)2]n·0.6(C2H5OH)·1.4(H2O) with the AF/AF/F alternating sequence (HL = N′-((pyridine-2-yl)methylene)isonicotinohydrazide)

The reaction of manganese(II) and a tetradentate hydrazone ligand (L) led to the formation of a new 2D system, [Mn3(N3)4(L)2(H2O)2]n. Azido groups act as bridges between neighboring manganese atoms and mediate ferromagnetic and antiferromagnetic interactions between them. Interestingly, this complex exhibits a ferrimagnetic-like behavior.
