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

One new heterometallic dinuclear Schiff-base complex Mn(DMF)2Zn(salpn)Cl2 (1) (H2salpn = N,N′-bis(salicylidene)-1,3-diaminopropane) has been successfully constructed by the solvothermal reaction of Mn(ClO4)2, ZnCl2 and H2salpn, 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 Mn2+ and Zn2+ centers, in which they respectively present octahedral and tetrahedral coordination geometries. Each neutral molecule unit [Mn(DMF)2Zn(salpn)Cl2] is further connected by four intermolecular hydrogen bonding Csingle bondH⋅⋅⋅Cl and two Csingle bondH⋅⋅⋅O interactions from six adjacent units to form a three-dimensional supramolecular network with pcu α-Po 412⋅ 63 topology. Moreover, luminescence, antifungal and antimicrobial activities of the heteronuclear compound 1 have also been investigated.
