The Mn(II) ion in the title complex, [MnBr(2)(C(18)H(12)N(6))], is five-coordinated in a distorted square-pyramidal geometry by three N atoms of the tridentate 2,4,6-tri-2-pyridyl-1,3,5-triazine (tptz) ligand and two bromide anions. In the crystal, the pyridyl rings coordinated to the Mn atom are inclined slightly to their carrier triazine ring [dihedral angles = 8.0 (3) and 7.5 (3)°], whereas ...

Here we show effect of the polyamine polymer chain length to BET isotherms. According to IUPAC classification [1], all three polymers are fitting type 1 physical adsorption isotherm with H3 hysteresis (except for EDA having H2 hysteresis). Moreover, TG and TGA analysis of polymers triazine-ethylenediamine (EDA) and triazine-triethylenetetramine (TETA) are provided. Due to the similarities of th...

A new triazine functionalized hexagonally ordered covalent organic polymer (TRITER-1) has been synthesized via the Schiff-base condensation reaction between a tailor made triamine 1,3,5-tris-(4-aminophenyl)triazine (TAPT) and terephthaldehyde. This ordered porous polymer showed a high BET surface area (716 m(2) g(-1)) and an excellent CO2 uptake capacity of 58.9 wt% at 273 K under 5 bar pressure.

The title compound, C(19)H(17)ClN(4), was obtained from the reaction of 3-chloro-5,6-diphenyl-1,2,4-triazine with isobutyronitrile in the presence of lithium diisopropyl-amide as an unexpected product of covalent addition of isobutyronitrile carbanion to the C-5 atom of the 1,2,4-triazine ring. The 2,5-dihydro-1,2,4-triazine ring is essentially planar (r.m.s. deviation = 0.0059 Å) and the 5- an...
