Bis(?-azido-?N:N)bis-{(acetato-?O,O')[2,4,6-tris-(2-pyrid-yl)-1,3,5-triazine-?N,N,N]lead(II)}.

ABSTRACT: The complete dinuclear title complex, [Pb(2)(C(2)H(3)O(2))(2)(N(3))(2)(C(18)H(12)N(6))(2)], is generated by the application of a crystallographic centre of inversion. The Pb(II) atom is coordinated by three N atoms of the tridentate ligand, two O atoms derived from an asymmetrically coordinating acetate ligand, and two azido-N atoms derived from two asymmetrically bridging azido ligands. The metal coordination geometry can be described as a square anti-prism with one position occupied by an unseen lone pair of electrons. In the ligand, the two coordinating pyridine rings are almost co-planar with the central pyrazine ring [dihedral angles = 0.47?(17) and 0.83?(18)°], but the terminal ring is twisted [dihedral angle = 19.76?(18)°]. In the crystal, the presence of ?-? inter-actions [ring centroid distance between pyridyl rings = 3.581?(2)?Å] leads to supra-molecular chains along the a-axis direction.

2,4,6-Tris(2,4-dimethyl-phen-yl)-1,3,5-triazine.

Project description:Two virtually superimposable mol-ecules comprise the asymmetric unit of the title compound, C(27)H(27)N(3). The range of dihedral angles between the central 1,3,5-triazine ring and the attached benzene rings is 20.88?(14)-31.36?(14)°, and the shape of each mol-ecule is of a flattened bowl. The crystal packing features weak C-H?? bonds and ?-? inter-actions between triazine and benzene rings [centroid-centroid separations = 3.7696?(17) and 3.7800?(18)?Å] that result in the formation of supra-molecular layers in the ac plane. The crystal studied was a non-merohedral twin with a minor twin component of 20.7?(3)%.

Project description:In the title compound, [Ni(CHO(2))(2)(C(18)H(12)N(6))(H(2)O)(2)](n), the Ni(II) ion, lying on a crystallographic inversion center, has a distorted octa-hedral coordination comprising two water ligands, two O-atom donors from formate ligands and two N-atom donors from the 2,4,6-tris-(4-pyrid-yl)-1,3,5-triazine ligands. These ligands bridge the Ni(II) complex units, forming zigzag chains along the c axis. Adjacent chains are linked by O-H?O hydrogen bonds, forming a three-dimensional supra-molecular network.

Heterometallic Coordination Polymer Gels Supported by 2,4,6-Tris(pyrazol-1-yl)-1,3,5-triazine.

Project description:Complexes of type [M(tpt)2]X2 (M2+ = Fe2+, Co2+, Ni2+; tpt = 2,4,6-tri{pyrazol-1-yl}-1,3,5-triazine; X- = BF4 - or ClO4 -) crystallize in a cubic lattice, with the metal ion and ligand conformation showing unusual symmetry-imposed disorder. Addition of 1 equiv AgX to the corresponding preformed [M(tpt)2]X2 salt in concentrated MeNO2 solution affords thixotropic gels. Gelation was not observed in analogous reactions using [Mn(tpt)2][ClO4]2, or from reactions in other, more donating solvents. Scanning electron microscopy (SEM) images from dilute solutions of the reagents confirmed the fibrous microstructure of the gels and their homogeneous elemental composition. However, energy-dispersive X-ray data show a reduced Fe/Ag ratio compared to the Co/Ag and Ni/Ag gels, where a 1:1 ratio of metals is evident. More concentrated gels decomposed to silver nanoparticles during SEM sample preparation. Mass spectrometry and 1H NMR indicate that silver induces partial ligand displacement reactions in [Fe(tpt)2]2+ and [Co(tpt)2]2+, but not in [Ni(tpt)2]2+. Hence, the strength of the gels, which follows the order M = Mn (no gel) < Fe < Co < Ni, correlates with the stability of octahedral [M(tpt)2]2+ under gelation conditions. Iron(II) complexes of the related ligands 2,4,6-tri{pyrazol-1-yl}pyridine (tpp) and 2,4,6-tri{pyrazol-1-yl}pyrimidine (tpym) did not undergo gelation with silver salts under the above conditions. The unique properties of tpt as a gelator in this work may reflect the crystallographically observed ability of metal-coordinated tpt to chelate to exogenous silver ions, through its pendant pyrazolyl group and triazinyl N donors. In contrast, the pendant azolyl substituents in silver complexes of the nongelators tpp and tpym only bind exogenous silver in monodentate fashion.
