Abstract: Computer Program Abstracts The category Computer Program Abstracts provides a rapid means of communicating up-to-date information concerning both new programs or systems and significant updates to existing ones. Following normal submission, a Computer Program Abstract will be reviewed by one or two members of the IUCr Commission on Crystallographic Computing. It should not exceed 500 words in length and should follow the standard format given on page 189 of the June 1985 issue of the Journal [J. Appl. CrysL (1985). 18, 189190] and on the World Wide Web at http://www.iucr. ac. uk/journals/jac/software/.

TL;DR: Two new heteroleptic iridium(III) complexes synthesized and fully characterized exhibit luminescence bands centered above 650 nm, attributed to a charge-transfer triplet state located on the pyr(2)bpy ligand, lying at lower energy than the strongly emitting Ir-ppy→bpy triplet states of the complexes lacking the pyrene fragments.
Abstract: Two new heteroleptic iridium(III) complexes [Ir(ppy)2(pyr2bpy)][PF6] ([1a][PF6]) and [Ir(dfppy)2(pyr2bpy)][PF6] ([2a][PF6]), where Hppy = 2-phenylpyridine, Hdfppy = 2-(3,5-difluorophenyl)pyridine, and pyr2bpy = 5,5′-bis(pyren-1-yl)-2,2′-bipyridine, have been synthesized and fully characterized The single-crystal structures of pyr2bpy and the complexes 4{[1a][PF6]}·2CH2Cl2·9H2O and [2a][PF6]·025CH2Cl2·H2O have been determined The effect of the pyrene substituents on the electronic properties is investigated through a comprehensive photophysical and theoretical study on the two complexes in comparison to reference complexes without substituents on the ancillary ligand ([1][PF6] and [2][PF6]) and by making absorption and luminescence titrations of ligand pyr2bpy Both theory and experiment show that the intense and broad band appearing in the 400–500 nm region of the absorption spectra of [1a][PF6] and [2a][PF6] is due to intramolecular charge-transfer (ICT) transitions from the pyrene substituents to the

TL;DR: In this article, a blue light emitting phenylene-vinylene functionalized terpyridine conjugate was developed as a "turn-on" fluorescent probe exhibiting a high selectivity towards toxic Cd2+ without interference by other competing metal ions in submicromolar level.
Abstract: A blue light emitting phenylene–vinylene functionalized terpyridine conjugate was developed as a ‘turn-on’ fluorescent probe exhibiting a high selectivity towards toxic Cd2+ without interference by other competing metal ions in submicromolar level. The specific response towards Cd2+ and the ability in discriminating Zn2+ offer an opportunity to develop on-site test paper kit for practical utility to detect toxic Cd2+.

TL;DR: The cobalt(III) clusters of types 1 and 2 have been found to effectively promote the TBHP oxidation of benzylic alcohols under homogeneous conditions to produce the corresponding carbonyl compounds.
Abstract: Two series of oxo-bridged Co(III) complexes of the type Co4O4(O2CC6H4-X)4(py)4 (1) and Co4O4(O2CC6H4-X)4(4-Mepy)4 (2), where X = H (a), Me (b), MeO (c), Cl (d), NO2 (e), have been synthesized and characterized in detail. The molecular structures of the complexes consist of a cubelike Co4(μ3-O)4 core having Co and O atoms at alternate vertices with carboxylato ligands bridging the Co3+ ions along four face diagonals of the approximate cube. Nitrogen atoms from pyridyl ligands complete the distorted-octahedral coordination around each Co(III). These neutral Co(III) complexes undergo a nearly reversible one-electron oxidation involving the redox couple [Co4III(μ3-O)4]4+ ↔ [Co3IIICoIV(μ3-O)4]5+ at potentials (∼0.7−1.0 V) that linearly depend on the electronic influence of X. The cobalt(III) clusters of types 1 and 2 have been found to effectively promote the TBHP oxidation of benzylic alcohols under homogeneous conditions to produce the corresponding carbonyl compounds.
