N‐Donor Ligand Coordination Polymers of Cu^II, Zn^II, and Cd^II Obtained at Elevated Temperature and Pressure

Abstract

Reactions of Copper(II), Zinc(II), and Cadmium(II) nitrate with 2,4,6‐tris(dipyridin‐2‐ylamino)‐1,3,5‐triazine (dpyatriz) at elevated temperature and pressure lead to new 1D coordination polymers which exhibit solid‐state structures significantly different from those obtained at room temperature and atmospheric pressure. In addition, these coordination compounds exhibit unusual anion–π interactions. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2005)

Multimetallic compounds containing cyclometalated Ir(III) units: Synthesis, structure, electrochemistry and photophysical properties

“…Since it was felt that that metal-coordination of triazine N atoms cause ring hydroxylation, we used ligands cddt and tdat where di-2-pyridylamino groups are present [48][49][50][51]. In these cases, the pyridyl units are far away from the central ring and hence metal coordination to these groups is not expected to affect the triazine ring.…”

Coordination Dependence of Magnetic Properties within a Family of Related [FeII2] Complexes of a Triazine‐Based Ligand

“…[11] In these products, the dpyatriz ligands have their three dipyridylamine (dpya) chelating units engaged in coordination. By contrast, the analogous reaction with Co II conduces to the dimeric complex [Co 2 -(dpyatriz) 2 [12] Despite the variety of coordination modes and structures observed, none of the complexes described so far shows the dpyatriz ligand using the N-donor of the triazine ring for coordination to a metal atom. (3), as revealed by single-crystal X-ray crystallography.…”

Half-sandwich ruthenium, rhodium and iridium complexes containing dipyridyl amine based ligands

“…In these complexes the amine nitrogen of dipyridylamine has trigonal planar geometry as in the free ligand tdat (Fig. S1) [45][46][47][48][49][50][51][52][53][54][55]. It may be attributed to the involvement of lone pair of electrons on secondary amine in conjugation with the central triazine ring.…”
