Discrete Metal Complexes of Two Multiply Armed Ligands

Abstract

The syntheses and metal complexes of 1,2,4,5-tetrakis(8-quinolyloxymethyl)benzene(1) and hexakis(8-quinolyloxymethyl)benzene (2) are described. X-Ray crystal structures are reported of the free ligand 1, a binuclear silver(I) and a tetranuclear copper(I) complex of 1, as well as a binuclear cobalt(II) and trinuclear palladium(II) and silver(I) complexes of 2.Within these discrete metal complexes the ligands are found to adopt a range of coordination modes, with considerable variation in the relative orientations of the ligand arms as a result of the flexibility imparted by the CH 2 O linker units.

A series of coordination polymers assembled from d10 metals and a new multidentate N-donor ligand: syntheses, structures, and photoluminescent properties

“…Hexakis(bromomethyl)benzene, 7 (m-phenol)-1,2,4-triazole 8 and the htpmb 9 were synthesized according to the literature. Other reagents and solvents were purchased from commercial sources and used without further purification.…”

An overview on synthetic strategies for the construction of star-shaped molecules

“…of Ag + ). [109][110][111] Cui and Wang tetrakis(phosphonate) 252a. Deprotection of TBDMS proceeded to form 254a 0 in a quantitative yield, followed by esterication with 4-oxo-4-(penta-1,4-dien-3-yloxy)butanoic acid 255 furnished SSMs 256a with four pentadiene tails in good yield (63%).…”

The occurrence and representation of three-centre two-electron bonds in covalent inorganic compounds

“…In addition to the ability of P, As, and Sb of ER 3 ligands to bridge two metal centres, the nitrogen atom of acetonitrile has also recently been shown to bind in a similar manner in a variety of compounds.
