The first Mn–Zn heterometallic dinuclear compound based on Schiff base ligand N, N′-bis(salicylidene)-1,3-diaminopropane

Abstract One new heterometallic dinuclear Schiff-base complex Mn(DMF) 2 Zn(salpn)Cl 2 ( 1 ) (H 2 salpn = N,N′-bis(salicylidene)-1,3-diaminopropane) has been successfully constructed by the solvothermal reaction of Mn(ClO 4 ) 2 , ZnCl 2 and H 2 salpn, and characterized by element analysis, IR spectroscopy and thermal analysis, as well as single crystal X-ray diffraction. The result reveals that compound 1 is heterodinuclear with Mn 2+ and Zn 2+ centers, in which they respectively present octahedral and tetrahedral coordination geometries. Each neutral molecule unit [Mn(DMF) 2 Zn(salpn)Cl 2 ] is further connected by four intermolecular hydrogen bonding C H⋅⋅⋅Cl and two C H⋅⋅⋅O interactions from six adjacent units to form a three-dimensional supramolecular network with pcu α -Po 4 12 ⋅ 6 3 topology. Moreover, luminescence, antifungal and antimicrobial activities of the heteronuclear compound 1 have also been investigated.
