In the title compound, [Co(C10H16O4)] n , the Co(II) atom is bonded in a slightly distorted tetra-hedral environment by four O atoms from the bridging sebacate dications, comprising two separate half-ligands which lie across crystallographic inversion centres. In the three-dimensional network coordination polymer, there are two different spatial extensions of Co(II) atoms, one with the Co(II) atoms lying parallel to (100) [Co⋯Co = 4.653 (1) Å], the other lying parallel to (010) [Co⋯Co = 4.764 (1) Å].

Fusarium solani biomass plays a significant role in water pollution remediation due to its ability to sequester heavy metals, particularly cobalt (Co(II)) and cadmium (Cd(II)), which pose severe environmental and health risks. This study aimed to identify fungi from sewage-contaminated sites and evaluate their efficiency in absorbing and reducing Co(II) and Cd(II) ions. The biosorption potential of irradiated Fusarium solani biomass for removing Co(II) and Cd(II) ions from aqueous solutions was investigated.

Reaction of Co(NCS) with 4-methyl-pyridine in water leads to the formation of single crystals of the title compound, [Co(NCS)(CHN)] . The asymmetric unit consists of two crystallographically independent thio-cyanate anions and two crystallographically independent 4-methyl-pyridine coligands in general positions, as well as of two different Co cations, of which one is located on a twofold rotational axis, whereas the second occupies a center of inversion. The methyl H atoms in both 4-methyl-pyridine ligands are disordered and were refined using a split model.

Two artificial imidazole-derived nucleobases, Im (3H-imidazo[4,5-f]quinolin-5-ol) and Im (imidazole-4-carboxylate), were introduced into short DNA duplexes to systematically investigate their thermal stability upon metal ion coordination. Metal-mediated base pairs are formed with the 3d metal ions Co, Ni and Zn, as well as with the lanthanoid ions Eu and Sm, which induce a thermal stabilization of up to 8 °C upon binding. The latter are the first lanthanoid-mediated base pairs involving only four donor atoms that result in a significant duplex stabilization.

The asymmetric unit of the title compound, [Co(CBrO)(CHN)(HO)] or [Co(Brbdc)(im)(HO)] , comprises half of Co ion, tetra-bromo-benzene-dicarboxylate (Brbdc), imidazole (im) and a water mol-ecule. The Co ion exhibits a six-coordinated octa-hedral geometry with two oxygen atoms of the Brbdc ligand, two oxygen atoms of the water mol-ecules, and two nitro-gen atoms of the im ligands. The carboxyl-ate group is nearly perpendicular to the benzene ring and shows monodentate coordination to the Co ion.
