“…Both Ag1 and Ag2 are linearly coordinated to −CN ligands (Ag1 is coordinated to N end of the equatorial −CN ligand whereas Ag2 is linked to the axial −CN ligand) of AgNNPs through weak interactions. The peak around 1300–1500 cm –1 is further supported literature. , …”

“…The signals appeared around 1360 and 1528 cm −1 in Raman spectra of AgNNPs (Figure 2) may be due to the presence of two kinds of M−L bonds (Ag1•••NC and Ag2•••NC) as per the published literature. 31,33,34 According to Rodri ́guez-Hernańdez and co-workers 31 there are two kind of silver atoms (Ag1 and Ag2) present in the silver nitroprusside. Both Ag1 and Ag2 are linearly coordinated to −CN ligands (Ag1 is coordinated to N end of the equatorial −CN ligand whereas Ag2 is linked to the axial −CN ligand) of AgNNPs through weak interactions.…”

“…The peak around 1300−1500 cm −1 is further supported literature. 33,34 The shifting of the −CN stretching signal from around 2125 cm −1 (AgNNPs) to 2186 cm −1 (SNP) is due to the exchange of sodium ion by silver ion in rhe ionic sphere of nitroprusside. The decrease in ν(CN) stretching of AgNNPs compared to that for SNP is due to decline in polarity between Ag−Fe than Na−Fe in nitroprusside complex.…”

Therapeutic agents harboring both wound healing and antibacterial activities have much demand in biomedical applications. Development of such candidates with clinically approved materials adds more advantages toward these applications. Recently, silver metal complex nanomaterials have been playing a major role in medical uses especially for antibacterial activity and wound healing. In this report, we designed and synthesized silver nitroprusside complex nanoparticles (abbreviated as AgNNPs) using sodium nitroprusside and silver nitrate (both are FDA approved precursors). The nanoparticles (AgNNPs) were thoroughly characterized by various physicochemical techniques such as XRD, FTIR, TGA, DLS, EDAX, Raman, ICP-OES, HRTEM, and FESEM. The cell viability assay in normal cells (EA.hy 926 cells, NIH 3T3) using MTT reagents and CEA assay (CEA: Chick embryo angiogenesis assay) in fertilized eggs demonstrate the biocompatibility of AgNNPs. These nanoparticles show effective antibacterial activity against both Gram positive and Gram negative bacteria through membrane and DNA damage. Additionally, AgNNPs accelerate the wound healing in C57BL6 mice by altering the macrophages from M1 to M2. Considering the results together, the current study may offer the development of new silver nanocomplex nanomaterials that shows synergistic effect on antibacterial activity and wound healing (2-in-1-system). To the best of our knowledge, this is the first report for the synthesis, characterization, and biomedical applications of silver nitroprusside nanoparticles.

Among the recent developments in metal-organic frameworks (MOFs), porous layered coordination polymers (CPs) have garnered attention due to their modular nature and tunable structures. These factors enable a number of properties and applications, including gas and guest sorption, storage and separation of gases and small molecules, catalysis, luminescence, sensing, magnetism, and energy storage and conversion. Among MOFs, two-dimensional (2D) compounds are also known as 2D CPs or 2D MOFs. Since the discovery of graphene in 2004, 2D materials have also been widely studied. Several 2D MOFs are suitable for exfoliation as ultrathin nanosheets similar to graphene and other 2D materials, making these layered structures useful and unique for various technological applications. Furthermore, these layered structures have fascinating topological networks and entanglements. This review provides an overview of different aspects of 2D MOF layered architectures such as topology, interpenetration, structural transformations, properties, and applications.

“…systems and coordination polymers are quite remarkable in coordination chemistry due to their new topologies and different potentials applications like a luminescence, adsorption, catalysis, gas storage, and magnetism, etc. (1)(2)(3)(4). In many cases, it is very difficult to establish an interaction between the synthesis conditions and the structural properties (5)(6)(7).…”

Two novel complexes, [Cu2(-dmg)2(2-meim)4]•5H2O (1) and {[Cd(-dmg)(2-meim)2]•H2O}n (2), with 2-methylimidazole (2-meim) and 2,2-dimethylglutarate (dmg) as ligands, have been systematically prepared by a conventional method. As a result, organic-inorganic crystalline solids were obtained. Their solid-state structures have been solved with elemental analysis, fourier transform infrared spectroscopy (FTIR) Powder X-ray diffraction (PXRD) and single-crystal X-ray diffraction (XRD). The Cu(II) ions displayed a distorted square planar geometry (CuO2N2), while Cd(II) ions showed a distorted octahedral geometry (CdO4N2). Complex 1 formeda dimeric structure, in which the Cu(II) ions were bridged by dmg. These dimeric units were extended to the 3D supramolecular structure with hydrogen bonding and -bonding interactions. Complex 2 formed a 1D polymeric structure, where the Cd(II) ions were linked by dmg ligand to form 1D zigzag polymer layers which were further extended in 3D supramolecular structure through molecular interactions as complex 1. Moreover, the thermal properties of the complexes were reported.
