A novel three-dimensional heterometallic compound: templated assembly of the unprecedented planar “Na⊂[Cu₄]” metalloporphyrin-like subunits

Abstract

A 3D heterometallic compound, [Cu4Na4(TzDC)4(H2O)7]n (H3TzDC = 1,2,3-triazole-4,5-dicarboxylic acid), which contains unprecedented planar "Na within [Cu4]" metalloporphyrin-like subunits, was synthesized by hydrothermal reactions involving in situ formation of the ligand and templated assembly of the metalloporphyrin-like subunits.

Acentric and chiral heterometallic inorganic–organic hybrid frameworks mediated by alkali or alkaline earth ions: synthesis and NLO properties

“…a lack of preferred geometrical orientation and coordination number, and the ionic nature of the metal-carboxylate oxygen bonds). [46][47][48][49][50][51][52] However, in hydrothermal synthesis where water is used as a reaction medium, they tend to form stable hydration complexes that reside within the framework and act only as a counter ion. In the absence of water, they have a great opportunity to coordinate to carboxylate oxygen atoms and participate in the network construction.…”

A series of novel chiral lanthanide coordination polymers with channels constructed from 16Ln-based cage-like building units

“…The coordination chemistry of H 3 tda with transition metals and alkali metals has been studied in recent years, 17,18 and our aim is to investigate the coordination chemistry of Ln-tda, and we hope to obtain novel complexes with specific structures and properties. Seven isostructural complexes were successfully isolated by using the same synthetic techniques.…”

Two complexes based on 1H-1,2,3-triazole-4,5-dicarboxylic acid: hydrothermal synthesis, crystal structures and spectral properties

“…The H 3 tda ligand (1H-1,2,3-triazole-4,5-dicarboxylic acid) can be partially or fully deprotonated acting in different coordination modes [9,13,18] when coordinating to 1H-1,2,3-Triazole-4,5-dicarboxylic acid 2991 metal ions under different conditions; two coordination modes have been observed in 1 and 2 ( figure 9). In 1, H 3 tda is fully deprotonated to tda 3À and adopt hexadentate coordination mode chelating three Zn(II) ions, while in 2 Htda 2À adopt tridentate coordination mode connecting two Co(II) ions.…”
