A new dimension in pincer chemistry: organometallic chemistry of iridium complexes the phosphine-based macrocyclic ligand PNP-14.

The title compound, C(46)H(40)N(4)O(2)·0.33C(6)H(12), was obtained unintentionally as a product of an attempted synthesis of a cadmium(II) complex of the [2,6-{PhSe(CH(2))(2)N=CPh}(2)C(6)H(2)(4-Me)(OH)] ligand. The full tetra-imino-diphenol macrocyclic ligand is generated by the application of an inversion centre. The macrocyclic ligand features strong intra-molecular O-H⋯N hydrogen bonds. The ...

The structure of the title compound, [Cu(ClO4)2(C16H38N6)] has been determined from synchrotron data, λ = 0.62988 Å. The asymmetric unit comprises one half of the Cu(II) complex as the Cu(II) cation lies on an inversion center. It is coordinated by the four secondary N atoms of the macrocyclic ligand and the mutually trans O atoms of the two perchlorate ions in a tetra-gonally distorted octa-he...

A mononuclear nonheme ferric-peroxo complex bearing a macrocyclic tetradentate N4 ligand, [(TMC)Fe(III)-O2]+, was prepared and used in mechanistic studies of aldehyde deformylation; a catalytic aldehyde deformylation by a nonheme iron(II) complex, [Fe(II)(TMC)]2+, and molecular oxygen is reported as well.

Abstract A unique family of chiral peraza N 6 ‐macrocyclic ligands, which are conformationally rigid and have a tunable saddle‐shaped cavity, is described. Utilizing their manganese(I) complexes, the first example earth‐abundant transition metal‐catalyzed asymmetric formal anti‐Markovnikov hydroamination allylic alcohols was realized, providing practical access to synthetically important γ‐amin...

Using scanning tunneling microscopy (STM), electrospray ionization mass spectrometry (ESI-MS), and X-ray photoelectron spectroscopy (XPS), we demonstrate that a free [2]catenane consisting of two interlocking 30-membered rings (cat-30) can be deposited on a Ag(111) surface by vacuum sublimation without decomposition. The deposited cat-30 molecules self-organize as ordered dimer chain structures...

A series of luminescent fac-[Re(CO)3(L)(NN)](+) complexes, where L is a pyridine or an imidazole and NN is the 1,10-phenanthroline subunit of mixed donor pentadentate thioether crowns have been synthesised and their luminescence properties have been analysed. Then, heterometallic Re(i)/Au(i) complexes, with the Au(i) fragment bonded directly to the imidazole ligand, and heterometallic Re(i)/Ag(...

A new macrocyclic ligand (H2L) was synthesized by reaction of Acenaphthoquinone and oaminophenol. Then, its Co (II), Ni (II), Cu (II), Zn (II) and Cd (II) complexes were synthesized by the condensation method. Macrocyclic ligand (H2L) and Co(NO3)2.6H2O, Ni(NO3)2.6H2O, Cu(NO3)2.6H2O, ZnCl2.2H2O and CdCl2.2H2O respectively. The ligand and its complexes have been characterized by IR, H, UV–Vis spe...
