AI Article Synopsis
- The complex [Hg(CN)(2)(C(3)H(8)N(2)S)(2)] features a mercury(II) atom with irregular tetrahedral coordination, involving two cyanide carbon atoms and two thione sulfur atoms from N,N'-dimethyl-thio-urea.
- The geometry shows a significant deviation from ideal tetrahedral angles, with a NC-Hg-CN bond angle of 148.83°.
- The molecular structure is stabilized by intra-molecular N-H⋯S interactions, while inter-molecular hydrogen bonds create a two-dimensional network in the crystal.
Article Abstract
In the title complex, [Hg(CN)(2)(C(3)H(8)N(2)S)(2)], the Hg(II) atom is located on a twofold rotation axis. It is four-coordinate having an irregular tetra-hedral geometry composed of two cyanide C atoms [Hg-C = 2.090 (6) Å] and two thione S atoms of N,N'-dimethyl-thio-urea (dmtu) [Hg-S = 2.7114 (9) Å]. The NC-Hg-CN bond angle of 148.83 (13)° has the greatest deviation from the ideal tetra-hedral geometry. The mol-ecular structure is stabilized by intra-molecular N-H⋯S inter-actions involving dmtu units related by the twofold symmetry. In the crystal, inter-molecular N-H⋯N(CN) hydrogen-bonding inter-actions link symmetry-related mol-ecules into a two-dimensional network in (110).

Two new zinc(II) complexes, tri-ethyl-ammonium di-chlorido-[2-(4-nitro-phen-yl)-4-phenyl-quinolin-8-olato]zinc(II), (CHN){Zn(CHNO)Cl] (), and bis-(tri-ethyl-ammonium) {2,2'-[1,4-phenyl-enebis(nitrilo-methyl-idyne)]diphenolato}bis-[di-chlorido-zinc(II)], (CHN)[Zn(CHNO)Cl] (), were synthesized and their structures were determined using ESI-MS spectrometry, H NMR spectroscopy, and single-crystal X-ray diffraction. The results showed that the ligands 2-(4-nitro-phen-yl)-4-phenyl-quinolin-8-ol () and ,'-bis-(2-hy-droxy-benzyl-idene)benzene-1,4-di-amine () were deprotonated by tri-ethyl-amine, forming the counter-ion EtNH, which inter-acts an N-H⋯O hydrogen bond with the ligand. The Zn atoms have a distorted trigonal-pyramidal () and distorted tetra-hedral () geometries with a coord-ination number of four, coordinating with the ligands N and O atoms.

Article Synopsis
- The compound [Zn(CHClNO)Cl] is a dinuclear zinc(II) complex that features three chlorido ligands and a penta-dentate ligand composed of quinolin-8-olato and bis-(pyridin-2-ylmeth-yl)amine.
- One zinc atom has a tetrahedral coordination with two chlorido ligands, while the other zinc atom is in a distorted trigonal-bipyramidal geometry, coordinating to a chlorido-O atom and three nitrogen atoms from the bis-(pyridin-2-ylmeth-yl)amine.
- The structure forms a three-dimensional network through several inter-molecular C-H⋯Cl hydrogen bonds, creating dimeric pairs and ribbon-like

The crystal structure of the title organic-inorganic hybrid salt, (CHN)[CdCl], (I), has been reported with four mol-ecules in the asymmetric unit in a monoclinic cell [Vassilyeva (2021 ▸). , , 7713-7722]. While using two different aldehydes in the oxidative cyclization-condensation involving CHNH·HCl to prepare a new monovalent cation with the imidazo[1,5-]pyridinium skeleton, a new polymorph was obtained for (I) in space group 1 and a unit cell with approximately half the volume of the monoclinic form.

The present study focuses on the synthesis and structural characterization of a novel dinuclear Cu complex, [tri-chlorido-copper(II)]-μ-chlorido-{bis-[2-hy-droxy-'-(propan-2-yl-idene)benzohydrazide]copper(II)} monohydrate, [CuCl(CHNO)]·HO or [Cu(H )(μ-Cl)CuCl]·HO [H = 2-hy-droxy-'-(propan-2-yl-idene)benzohydrazide]. The complex crystallizes in the monoclinic space group 2/ with one mol-ecule of water, which forms inter-actions with the ligands. The first copper ion is penta-coordinated to two benzohydrazine-derived ligands two nitro-gen and two oxygen atoms, and one bridging chloride, which is also coordinated by the second copper ion alongside three terminal chlorines in a distorted tetra-hedral geometry.
