A series of M[Au(CN)(2)](2)(analyte)(x) coordination polymers (M = Co, Ni; analyte = dimethylsulfoxide (DMSO), N,N-dimethylformamide (DMF), pyridine; x = 2 or 4) was prepared and characterized. Addition of analyte vapours to solid M(μ-OH(2))[Au(CN)(2)](2) yielded visible vapochromic responses for M = Co but not M = Ni; the IR ν(CN) spectral region changed in every case. A single crystal structu...

Abstract The availability of low-cost hole transport materials (HTMs) that are easy to process is crucial for the eventual commercialization perovskite solar cells (PSCs), as commonly used HTM (Spiro-OmeTAD) expensive, and its processing complex. In this study, we synthesized an amorphous molecular material (termed TPA-glass) from condensation 2-mexylamino-4-methylamino-6-(4-aminophenylamino)-1...

A new tris-(2-aminoethyl)amine (TREN) capped tripodal Schiff base ligand has been developed by mimicking structural features of a natural siderophore, Bacillibactin, by substituting the catechol units with salicylaldehyde and employing amino acid as spacer. Synthesis of the ligand N-[2-[bis[2-[[2-[(2-hydroxyphenyl)methylamino]acetyl] amino]ethyl]amino]ethyl]-2-[(2-hydroxyphenyl)methylamino]...

1. Cyanide hemochromogen probably contains one cyanide group per heme group. 2. The equilibrium between pyridine hemochromogen and its components, pyridine and reduced heme, is complicated to an unknown extent by the precipitation of reduced heme and the aggregation of pyridine hemochromogen. 3. These complications were not taken into account in R. Hill's experiments on pyridine hemochromogen. ...

In the title compound, [Ru(C(13)H(7)Cl(2)N(5))(C(15)H(11)N(3))](PF(6))(2)·2CH(3)CN, the Ru(II) atom is coordinated in a distorted octa-hedral geometry by a tridentate 2,2':6',2''-terpyridine ligand and a tridentate 2,6-bis-(5-chloro-pyrimidin-2-yl)pyridine ligand. Least-squares mean-plane distortions of only 1.72 (2) and 2.91 (2)° of the pyrimidyl rings with respect to the central pyridine are ...
