“…For instance, in healthcare, complex compounds serve as contrast agents in Magnetic Resonance Imaging (MRI), thereby aiding in the enhancement of tissue visualization (Chen et al, 2022). In magnetic materials, complex compounds find utility as thin-film-free sensors (Baran et al, 2020). Concurrently, complex compounds are harnessed within the industrial sector for corrosion inhibition purposes (Zaidi et al, 2023).…”

The synthesis of the bis-acetylacetonate zink (II) monohydrate complex [Zn(acac)2(H2O)] has been conducted. FTIR analysis, TGA-DSC, and SEM micrographic analysis performed complex characterization. The yield of the complex compound [Zn(acac)2(H2O)] was 36.24% using NaOH as a pH regulator. Based on the FTIR characterization of the typical absorption complex [Zn(acac)2(H2O)] appears at 763.88 cm-1 for Zn-O, C-H at 933.9 cm-1 and 1020 cm-1, C=C and C=O at 1516 cm-1, 1610 cm-1 and OH at 3450 cm-1 respectively. Thermal analysis of the complex shows that the decomposition temperature was obtained at 186oC. Based on the micrographic results, the complex has a non-uniform surface relief. The complex has an even distribution of pores with non-uniform pore sizes. Zn particles are deposited on the complex surface with various sizes to produce pores on the solid surface.

“…Nowadays special attention is focused on the compounds with complex crystal structures whose magnetic properties result from multiple magnetic sublattices. Such a distribution of the magnetic moments leads to the appearance of such phenomena as noncollinear magnetic structures and the coexistence of ferro-and antiferromagnetic components of the magnetic structure (Baran et al, 2020). In recent years, the compounds with the general formula of R 5 T 2 In 4 , where T is Ni (Zaremba et al, 1991), Pd (Sojka et al, 2008) or Pt (Zaremba et al, 2007), have been the subject of attention due to their striking physical properties (Tyvanchuk et al, 2010;Provino et al, 2012;Gondek et al, 2012;Szytuła et al, 2013Szytuła et al, , 2014Ritter et al, 2015;Zhang et al, 2018;Baran et al, 2021;Hayyu et al, 2024).…”

Results of the neutron powder diffraction measurements carried out for R 5Pt2In4 (R = Tb–Tm) are reported. The compounds crystallize in an orthorhombic crystal structure of the Lu5Ni2In4-type with the rare earth atoms occupying three different sublattices. Neutron diffraction data reveal that at low temperatures the rare earth magnetic moments order below the critical temperature equal to 105, 93, 28, 12 and 3.8 K for R = Tb, Dy, Ho, Er and Tm, respectively. With decreasing temperature the rare earth magnetic moments at the 2a and 4g2 sites order first, while the moments at the 4g1 site order at lower temperatures. Ferrimagnetic order along the c axis, described by the propagation vector k 1 = [0, 0, 0], develops in Tb5Pt2In4 below the Curie temperature (T C = 105 K). At lower temperatures, an antiferromagnetic component in the ab plane appears. The component is incommensurate with the crystal structure (k 2 = [0, 0.66, ½]), but it turns into a commensurate one (k 3 = [0, 0, ½]) with decreasing temperature. Antiferromagnetic order along the c axis, described by k 4 = [½, 0, 0], is found in Dy5Pt2In4 below the Néel temperature (T N = 93 K). The k 4-related component disappears below 80 K and the magnetic structure transforms into a ferro/ferrimagnetic one described by k 1 = [0, 0, 0]. Further decrease in temperature leads to the appearance of an incommensurate antiferromagnetic component within the ab plane below 10 K (k 2 = [0, 0.45, ½]), which finally turns into a commensurate one (k 5 = [0, ½, ½]). In Ho5Pt2In4, a sine-modulated magnetic structure with moments parallel to the c axis (k 6 = [⅓,0,0]) is observed below 28 K. With a decrease in temperature, new components, related to k 1 = [0, 0, 0] (bc plane) and k 4 = [½, 0, 0] (c axis), appear. The coexistence of two orderings – in the ab plane (k 1 = [0, 0, 0]) and a modulated one with moments along the b axis (k 7 = [k x , 0, 0]) – is found in Er5Pt2In4 below 12 K. Decreasing temperature leads to the order–order transformation of the k 1-related component to another one with magnetic moments still constrained to the ab plane and preserved value of the propagation vector (i.e. k 1 = [0, 0, 0]). Tm5Pt2In4 orders antiferromagnetically below T N = 3.8 K. Thulium magnetic moments lie in the ab plane, while the magnetic structure is described by k 5 = [0, ½ , ½]. The direction of magnetic moments depends on the rare earth element involved and indicates an influence of single ion anisotropy resulting from interaction with the crystalline electric field.
