The ligands 4′-{4-(N,N-diethylaminophenyl)}-3,2′:6′,3″-terpyridine (1) and 4′{4-(N,N-diphenylaminophenyl)}-3,2′:6′,3″-terpyridine (2) were prepared characterized, including the single crystal structure of 2. Along with their 4,2′:6′,4″-terpyridine isomers, 3 4, 1 2 reacted Co(NCS)2 under conditions growth by layering, using solvent mixtures MeOH CHCl3. structures [Co(NCS)2(1)]n·0.8nCHCl3, [Co(N...
In this paper, MnCl,.4H,O crystals with monoclinic structure, for the study of magnetic hyperfine field in magnetic crystal at low temperature, have been grown. To study the effect of impurities on T, (spin-lattice relaxation time), crystals with different percent of "Co impurities, from saturated mixed solution of MnCl,.4H,O and CoCl,.6H,O at temperature of 30Q'K, have been grown. The pe...
Four novel complexes [Co(H2O)4(sul)2] 1, [Co(2-ampy)2(sul)2] 2, [Co(H2O)2(1,10-phen) (sul)2] 3 and [Co(2,9-dimephen)(sul)2] 4 (sul = sulindac, 2-ampy = 2-amino pyridine, 1,10-phen = 1,10-phenanthroline and 2,9-dimeph = 2,9-dimethyl-1,10-phenanthroline) were prepared and characterized by IR, UV-Visible spectroscopy and magnetic properties. The crystal structures of complexes 1 and 4 were determi...
Co-crystallisation of 1,8-naphthalenedicarboxylic acid (1,8-nap) with trans-1-(3-pyridyl)-2-(4-pyridyl)ethylene (3,4-bpe) gives a discrete molecular solid-state assembly, 2(3,4-bpe).2(1,8-nap) 1, that is held together by four O-H...N hydrogen bonds wherein the diacid directs a regiocontrolled [2 + 2] photodimerization; the reaction occurs by way of a single-crystal-to-single-crystal transformat...
Flexible anionic metal-organic frameworks (MOFs) are transformed into neutral heterobimetallic systems via single-crystal-to-single-crystal processes invoked by cation insertion. These transformations are directed by cooperative bond breakage and formation, resulting in expansion or contraction of the 3D framework by up to 33% due to the flexible nature of the organic linker. These MOFs display...
