Dichlorido{2-[(2,6-dimethylphenyl)iminomethyl]pyridine-κ²N,N′}zinc

Abstract

In the asymmetric unit of the title compound, [ZnCl2(C14H14N2)], the central ZnII ion is four-coordinated in a distorted tetra­hedral environment by two N atoms of the ligand 2-[(2,6-dimethyl­phen­yl)imino­meth­yl]pyridine and two chloride anions. In the crystal, adjacent mol­ecules are connected through C—H⋯Cl hydrogen bonds between a C—H group of the ligand and a Cl− anion, leading to a chain-like structure along the b direction.

Five‐coordinate dinuclar cobalt (II), copper (II), zinc (II) and cadmium (II) complexes with 4‐bromo‐N‐(2‐pyridinylmethylene)benzenamine: Synthesis, characterisation and methyl methacrylate polymerization

“…The bond length of M–N imine increased by approximately 0.015–0.200 Å, ranging in size from ([ (bpma)Cu(μ – Cl)Cl] 2 ) < ([ (bpma)Co(μ – Cl)Cl] 2 ) < ([ (bpma)Zn(μ – Cl)Cl] 2 ) < ( [(bpma)Cd(μ – Br)Br] 2 ). The M–Cl bond lengths ranged from 2.2333(7) – 2.6460(6) Å while those of M–Br ranged from 2.5298(5) – 2.8244(5) Å. The double imine N(2)–C(6) distances of 1.289(2) Å ( [(bpma)Co(μ–Cl)Cl] 2 ), 1.279(6) Å ( [(bpma)Cu(μ–Cl)Cl] 2 ), 1.282(2) Å ( [(bpma)Zn(μ–Cl)Cl] 2 ) and 1.283(3) Å ( [(bpma)Cd(μ–Br)Br] 2 ) were in accepted range of carbon‐nitrogen double bonds.…”

(E)-N-(Pyridine-2-ylmethylene)arylamine as an Assembling Ligand for Zn(II)/Cd(II) Complexes: Aryl Substitution and Anion Effects on the Dimensionality and Luminescence Properties of the Supramolecular Metal–Organic Frameworks

“…Subsequently, the structures of ligands and Zn­(II)/Cd­(II) complexes have been characterized by means of 1 H NMR, IR, and EA spectroscopic studies, and for complexes Zn1 – Zn3 , Cd1 , Cd2 , Cd3a , Cd3b , Cd4 , and Cd5 additionally by single-crystal X-ray crystallography. The structure of complex Zn2 has been reported by Zhao et al, and there existed similar complexes in the literature, , but they simply show the structure of the unit cell rather than intermolecular interactions. Herein, we systematically investigated the effect of related alkyl substitution Schiff base ligands and intermolecular interactions (C–H ··· O/C–H ··· Cl hydrogen bonds and π ··· π interactions) in the organization and stabilization of supramolecular metal–organic frameworks (SMOFs).…”
