Abstract
The design and synthesis of magnets with low dimensionality is currently an attractive research topic. The reaction of a Schiff base metal complex with simple molybdate has led to the formation of a new {MnIII-Schiff-base}-decorated molybdate heterometallic cluster, [{Mn(salpn)(H2O)}3MoO4](CH3COO)·2H2O (1) (salpn = N,N’-(1,3-propylene)bis(salicylideneiminate)). The hybrid aggregate was characterized using a range of methods including elemental analysis, single crystal x-ray diffraction, Infrared spectra (IR) spectroscopy, and x-ray structural analysis. The crystals of 1 are hexagonal: P63/m, a = 14.027(5) Å, c = 17.487(5) Å, V = 1142.6(3) Å3. Structural analyses indicate that we report on the preparation of the first triple metallic-oligomer held by orthomolybdate. Density functional theoretical calculation (DFT) studies have been performed to calculate electronic structure and potential energy landscapes. Additionally, the magnetic property of 1 indicates an antiferromagnetic coupling between the metal centers in the complex.
Highlights
Organic-inorganic hybrids, a class of promising materials that simultaneously combine the remarkable features of both components into one material, presenting properties from either part of the distinctive building blocks, have become a focus of research interest in the past few decades [1,2,3,4].In recent years, more and more attention has been paid to Schiff base hybrids, because of their variety of architectures and fascinating topologies, and for their remarkable applications in magnetism, asymmetric catalysis, adsorption, and medicine [5,6,7,8]
As shown by bond valence sum (BVS) calculations [24] and XPS spectroscopy data, the Mo is in the +6 oxidation state (Table 2)
Structural analyses show that compound 1 represents the first example of tri-metallic-polymer decorated propylene)bis(salicylideneiminate))
Summary
Organic-inorganic hybrids, a class of promising materials that simultaneously combine the remarkable features of both components into one material, presenting properties from either part of the distinctive building blocks, have become a focus of research interest in the past few decades [1,2,3,4]. Various types of pure inorganic building blocks have been successfully introduced into Mn-salen molecular packing in crystals. This opens up a plethora of applications ranging from the synthesis of interesting magnetic compounds to the explorations of magnetic exchange [11,12,13,14,15]. This opens up a plethora of applications ranging from the synthesis of interesting magnetic compounds to the explorations of magnetic of 10.
