17,18-Dibromo-8-methyl-4,12-ditosyl-3,4,5,6,7,8,9,10,11,12,13,14-dodeca­hydro-2H-benzo[b][1,4,7,11,15]dioxatriaza­cyclo­hepta­decine

In the title compound, C31H39Br2N3O6S2, a 17-membered aza-macrocyclic ligand containing two ether O and three aza N atoms, the three pendant aromatic rings form an ‘E’ shape. The dihedral angles between the central benzene ring and the side ones are 17.8 (3) and 7.4 (3)°, and the dihedral angle between the tosyl rings is 10.6 (3)°. The methyl group is disordered over two orientations, with occupancies of 0.52 (15) and 0.48 (15)

4-[2-(Cyclo­hexa-1,4-dien-1-yl)eth­oxy]benzene-1,2-dicarbonitrile

In the title compound, C16H14N2O, the dihedral angle between the aromatic rings is 70.23 (6)°. The linking chain has a zigzag conformation. In the crystal, mol­ecules are linked by weak inter­molecular C—H⋯N hydrogen bonds, forming a zigzag chain along the c axis

The synthesis and characterization of a porphyrazine bearing aza-15-crown-5 moieties in the peripheral positions and its cobalt(II) complex

Biyiklioglu, Zekeriya/0000-0001-5138-214XWOS: 000253205200007The synthesis of novel metal-free (H-2-Pz) and metalloporphyrazines (MgPz and CoPz), peripherally substituted with eight aza-15-crown-5 moieties, is described. The novel compounds were characterized by elemental analysis, i.r, H-1 and C-13-n.m.r, UV-vis and m.s. spectral data

Synthesis, characterization and investigation of electrochemical and spectroelectrochemical properties of peripherally tetra 4-phenylthiazole-2-thiol substituted metal-free, zinc(II), copper(II) and cobalt(II) phthalocyanines

AKCAY, Hakki Turker/0000-0002-8502-9608; KOCA, ATIF/0000-0003-0141-5817;WOS: 000401593400074In this study novel peripherally tetra 4-phenylthiazole-2-thiol substituted metal-free phthalocyanine (4) and its zinc(II) (5), copper(II) (6) and cobalt(II) (7) derivatives were synthesized and characterized by a combination of various spectroscopic techniques such as FT-IR, H-1-NMR, UV-vis and MALDI-TOF mass. Electrochemical characterizations of metallo-phthalocyanine complexes were conducted by voltammetric and in situ spectroelectrochemical measurements.

The synthesis and characterization of a new (E,E)-dioxime containing 18-membered dithiadiazadioxamacrocyclic moieties and its mononuclear complexes

Biyiklioglu, Zekeriya/0000-0001-5138-214XWOS: 000253205200003A new (E,E)-dioxime, (21Z,22Z)-6,7,9,10,12,13-hexahydro-16H- benzo[h][1,4,7,16,10,13][1, 4,7,16,10,13]dioxadithiadiazacyclooctadecine-21,22(20H,23H)-dione dioxime (H (2) L) has been synthesized by reacting cyanogen-di-N-oxide (2) with (2-{[2-(2-{2-[(7-aminocyclohepta-1,4,6-trien-1-yl)thio]ethoxy}ethoxy)ethyl]thio}phenyl)amine. Mononuclear complexes of this ligand have been synthesized by reacting the vic-dioxime (H2L) with CuCl2, NiCl2.6H(2)O and CoCl2.6H(2)O respectively. The BF2+ capped Ni(II) and Co(III) complexes of the dioxime have been synthesized from. The new compounds were characterized by a combination of elemental analysis, H-1- and C-13-n.m.r, I.R. and m.s. spectral data
