AI Article Synopsis
- The title cocrystal features a 1:1 combination of two centrosymmetric Cu(II) complexes that include oxalate dianions and Schiff base ligands.
- In each molecule, the Cu(II) center displays a distorted octahedral structure influenced by the ligand arrangements, with one molecule containing a water and nitrate ion, and the other a methanol and nitrate ion at the axial positions.
- The crystal structure is stabilized through various hydrogen bonds (N-H⋯O, O-H⋯O, and N-H⋯N) that create a network linking the molecules together.
Article Abstract
The title cocrystal, [Cu(2)(C(2)O(4))(NO(3))(2)(C(7)H(9)N(3))(2)(H(2)O)(2)][Cu(2)(C(2)O(4))(NO(3))(2)(C(7)H(9)N(3))(2)(CH(4)O)(2)], is a 1:1 cocrystal of two centrosymmetric Cu(II) complexes with oxalate dianions and Schiff base ligands. In each mol-ecule, the Cu(II) centre is in a distorted octa-hedral cis-CuN(2)O(4) environment, the donor atoms of the N,N'-bidentate Schiff base ligand and the bridging O,O'-bidentate oxalate group lying in the equatorial plane. In one mol-ecule, a monodentate nitrate anion and a water mol-ecule occupy the axial sites, and in the other, a monodentate nitrate anion and a methanol mol-ecule occupy these sites. In the crystal structure, inter-molecular N-H⋯O, O-H⋯O and N-H⋯N hydrogen bonds link the mol-ecules into a network. Weak intra-molecular N-H⋯O inter-actions are also observed.

Potency and quantitative risk assessment are essential for determining safe concentrations for the formulation of potential skin sensitizers into consumer products. Several new approach methodologies (NAMs) for skin sensitization hazard assessment have been developed, validated, and adopted in OECD test guidelines. However, work is ongoing to develop NAMs for predicting skin sensitization potency on a quantitative scale for use as a point of departure (POD) in next-generation risk assessment (NGRA).

In the present study, biopolymeric Schiff base (SB) ligands were synthesized from chitosan and isatin. Consequently, their earth abundant transition metal complexes of cobalt and copper were synthesized. All compounds were extensively characterized using FTIR and UV spectroscopy, thermo-gravimetric (TG) analysis, X-ray powder diffraction (XRD) and FESEM (field emission scanning electron microscopy).

The healing of bacteria-infected wounds has long posed a significant clinical challenge. Traditional hydrogel wound dressings often lack self-healing properties and effective antibacterial characteristics, making wound healing difficult. In this study, a bioactive small molecule cross-linking agent 4-FPBA/Lys/4-FPBA (FLF) composed of 4-formylphenylboronic acid (4-FPBA) and lysine (Lys) was utilized to cross-link guar gum (GG) and a tannic acid/iron (TA/Fe) chelate through multiple dynamic bonds, leading to the formation of a novel self-healing hydrogel dressing GG-FLF/TA/Fe.

The root ducts play an important role in the plant's transport of nutrients from the soil. Based on the selective transport characteristics of plant roots, amino pillar[6]arene bionic porous root sub-nano channel membrane were constructed to remove Imazamox. Imazamox (IM) is an effective imidazolinone herbicide frequently utilized in soybean fields to control a wide range of annual grasses and broad-leaved weeds.

Stem cell implantation holds promise for enhancing bone repair, but risks of pathogen transmission and malignant cell transformation should not be ignored. Compared to stem cell implantation, recruitment of endogenous stem cells to injured sites is more critical for in situ bone regeneration. In this study, based on the acidic microenvironment of bone injury, an HG-AA-SDF-1α composite hydrogel with a dual-control intelligent switch function is developed by incorporating stromal cell-derived factor (SDF-1α), arginine carbon dots (Arg-CDs), and calcium ions (Ca) into the oxidized hyaluronic acid/gelatin methacryloyl (HG) hydrogel.
