The title compound, [Cu(C(6)H(8)N(2))(C(13)H(15)N(3))](ClO(4))(2), is a mixed ligand complex with the Cu(II) atom coordinated by (6-methyl-2-pyridylmeth-yl)(2-pyridylmeth-yl)amine, acting as a tridentate ligand, and 2-(2-amino-meth-yl)pyridine, as a bidentate ligand, leading to an N(5) square-pyramidal geometry. The amine H atoms are involved in hydrogen bonding to the perchlorate O atoms and t...

The asymmetric unit of the title compound, C(9)H(9)N(3)S, contains two crystallographically independent mol-ecules, in which the thia-diazole and tolyl rings are oriented at dihedral angles of 32.25 (3) and 74.50 (3)°. An intra-molecular C-H⋯S inter-action results in the formation of a five-membered ring. In the crystal structure, inter-molecular N-H⋯N hydrogen bonds link the mol-ecules into ch...

  Some of fused dihydrobenzo [4,5]imidazo [1,2-a] pyrmido [5,4-e] pyrmidin-3(4H)-amine  derivatives were synthesized,  theses derivatives derived from 4-amino-2-(4-chloro or bromophenyl) -1,2-dihydropyrimido[1,2-a] benzimidazole-3-carbonitrile (4,5), which prepared by reaction 1H-benzimidazol-2-amine (1) and p-chlorobenzaldehyde p-bromobenzaldehyde (2)  and malononitrile (3)...

In this work, a new synthesized Y-type zeolite with an Si/Al molar ratio of 2.5 (NaY) was modified with amines, in order to probe the influence of the modification of the adsorbent’s surface on CO2 adsorption. The three selected amines were diethanolamine, tetraethylenepentamine, and 2- methylaminoethanol. The surface nature of NaY was changed after amine modification, which causes a...

The title compound, C(21)H(27)N(7), was synthesized by reaction of tris-(2-amino-ethyl)amine and pyrrole-2-carbaldehyde in ethanol at room temperature. The structure is stabilized by intra- and inter-molecular C-H⋯N and N-H⋯N hydrogen-bonding inter-actions.

The title Schiff base, C(27)H(33)N(7), is a tripodal amine displaying C(3) symmetry, with the central tertiary N atom lying on the threefold crystallographic axis. The N-CH(2)-CH(2)-N conformation of the pendant arms is gauche [torsion angle = 76.1 (3)°], which results in a claw-like mol-ecule, with the terminal aniline groups wrapped around the symmetry axis. The lone pair of the apical N atom...
