Blue luminescent zinc(II) complexes with polypyridylamine ligands: crystal structures and luminescence properties

Crystallographic report: Diazido[bis(2‐pyridyl)amine]zinc(II) hydrate, [Zn(C10H9N3)2(N3)2]·H2O

“…1,2 The zinc centre is six-coordinated by four nitrogen donors of the pyridine rings, and two terminal nitrogen atoms of the azide anions (Fig. 1).…”

Dichloro(di-2-pyridylamine)zinc(II): a redetermination at 110 K

“…The synthesis and crystallization of (I) were performed according to the literature method of Ho et al (1999). Displacement ellipsoid plot of (I).…”

“…The title compound, [ZnCl 2 (C 10 H 9 N 3 )], has been investigated at 110 K. In contrast with the previously published roomtemperature structure [Ho et al (1999). J. Chem.…”

“…The crystal structure of dichloro[bis(2-pyridyl)amine]zinc(II), (I), has been published by Ho et al (1999) with a distorted non-planar geometry at the amine N atom, expressed by C-N-H angles of 106 (2) and 117 (2) and a rather long N-H distance of 1.12 (4) Å . In order to determine more precisely the environment of the amine N atom, we re-determined the structure at low temperature.…”

“…Data collection: COLLECT (Nonius, 1999); cell refinement: PEAKREF (Schreurs, 2005); data reduction: EVALCCD (Duisenberg et al 2003); method used to solve structure: coordinates taken from literature (Ho et al, 1999); program(s) used to refine structure: SHELXL97 (Sheldrick, 1997); molecular graphics: PLATON (Spek, 2003); software used to prepare material for publication: PLATON.…”
