In the title complex, [Cd(C(14)H(9)N(5))(NO(3))(H(2)O)(2)]NO(3), the Cd(II) ion is coordinated in a distorted penta-gonal-bipyramidal geometry. The equatorial sites are occupied by a 2-(1H-1,2,4-triazol-1-yl)-1,10-phenanthroline ligand in a tridentate coordination mode and a bis-chelating nitrate ligand. Two aqua ligands are coordinated at the axial sites. All non-H atoms in the equatorial plane are co-planar within 0.0673 Å. In the crystal, inter-molecular O-H⋯O and O-H⋯N hydrogen bonds connect the components into a two-dimensional network parallel to (001). In addition, there is a π-π stacking inter-action between symmetry-related benzene rings, with a centroid-centroid distance of 3.598 (3) Å.

Denitrification is fragile to toxic substances, while currently there are few regulation strategies for toxic substance-stressed denitrification. This study proposed a combined bio-promoter composed of basic bio-promoter (cytokinin, biotin, L-cysteine, and flavin adenine dinucleotide) and phosphomolybdic acid (PMo) to recover cadmium(II) (Cd(II)) stressed denitrification. By inhibiting 58.

Optimizing friction materials based on molecular diversity in a molecular framework system is an effective method to improve the output performance of triboelectric nanogenerators (TENGs). In this study, three cadmium(II) metal-organic frameworks (Cd-MOFs) with different cavities were synthesized solvothermally by the assembly of cadmium nitrate (Cd(NO)·4HO), 4',4'''-carbonylbis(([1,1'-biphenyl]-3,5-dicarboxylic acid)) (HCBBD), and trans-1,2-bis(4-pyridyl)ethylene (4,4'-bpe) via a solvent-regulated strategy. The topology and porosity of Cd-MOFs could be controlled effectively by the solvent constituents and were demonstrated to be closely related to their triboelectric behaviors.

The isomeric ligand L, a saturated analogue of 2,9-C-meso-Me[14]diene, on reflux with excess acrylonitrile afforded 1,8-N-pendant cyanoethyl derivative L. Interaction of L with cadmium(II) perchlorate, nitrate, acetate, and chloride salts produced six coordinated octahedral compounds, [Cd(L) (ClO)]∙2HO, [Cd(L) (NO)], [Cd(L) (CHCOO)], and [Cd(L)Cl], respectively. Further, axial substitution reactions between [Cd(L) (ClO)]∙2HO and KI, KBr, KCl, KSCN, and NaNO in a 1:2 ratio yielded six coordinated octahedral compounds, [Cd(L)I]∙HO, [Cd(L)Br]∙2HO, [Cd(L)Cl(ClO)]∙2HO, [Cd(L) (NCS)]∙HO, and [Cd(L) (NO) (ClO)]∙2HO, respectively.

Coordination polymers with a new rigid ligand 1,3-bis(1,2,4-triazol-1-yl)adamantane (L) were prepared by its reaction with cadmium(II) or silver(I) nitrates. Crystal structure of the coordination polymers was determined using single-crystal X-ray diffraction analysis. Silver formed two-dimensional coordination polymer [Ag(L)NO], in which metal ions are linked by 1,3-bis(1,2,4-triazol-1-yl)adamantane ligands, coordinated by nitrogen atoms at positions 2 and 4 of 1,2,4-triazole rings.
