Hydrothermal Preparation of Novel Cd(II) Coordination Polymers Employing 5-(4-Pyridyl)tetrazolate as a Bridging Ligand

Abstract

The reaction of 4-cyanopyridine with NaN(3) in the presence of H(2)O and a Lewis acid (CdCl(2)) affords a novel 3D pillared-layered fluorescent and phosphorescent coordination polymer Cd(3)(OH)(2)Cl(2)(4-PTZ)(2) (4-PTZ = 5-(4-pyridyl)tetrazolate) (1) while the direct reaction of CdCl(2) with H-PTZ gives the simpler species Cd(4-PTZ)(2)(H(2)O)(2). The solid-state structure and nature of 1 provide an indication of the type of materials that may be formed as intermediates in the Sharpless-Demko reaction for the generation of 5-substituted 1H-tetrazoles.

Synthesis, Crystal Structures and Photoluminescent Properties of Three Novel Cadmium(II) Compounds Constructed from 5‐Sulfoisophthalic Acid (H3SIP)

“…It is even more interesting that the [Cd 4 (µ 3 -OH) 2 ] cluster units are interconnected by the Cd(3)(µ 2 -OH) 2 (CO 2 ) unit into an unusual inorganic oxide layer. Although cadmium cluster units have been known to be present in coordination polymers, [6,[26][27][28] such clusterbased inorganic layers as subunits of a coordination polymer are still scarce. The layer has a 12-membered ring (A) with approximate dimensions of 3.8 ϫ 4.9 Å 2 , which is composed of Cd(3), Cd(4) and Cd(5) atoms and their equivalents linked by two µ 3 -OH, two µ 2 -OH and two carboxylate groups.…”

Supramolecular assembly of three d10 metal coordination polymers based on the naphthalene-1,8-dicarboxylate ligand: Syntheses, structures and luminescent properties

“…As a result, a large number of one-(1D), two-(2D), and three-dimensional (3D) metal-organic frameworks have been synthesized through weak interactions. Therefore, the weak interactions are very important in the self-assembly of supramolecular architectures [14][15][16][17][18].…”

In situ Synthesis, Crystal Structure, XPS and Fluorescent Property of a Novel Two-Dimensional Binuclear Copper(I) Tetrazole Complex

“…[8][9][10][11] As a result, there is much research concentrated on the crystallographic characterization of such intermediates containing metal ion and exploration of their applications in nonlinear optical, fluorescent (or phosphorescent), ferroelectric, and chiral properties.…”
