In the monomeric title titanium(III) compound, [Ti(C(12)H(21)N(2)Si)(2)Cl], the metal atom is surrounded by two N-silylated anilide ligands in an N,N''-chelating mode. The two ends of the N-Si-N chelating unit exhibit different affinity to the metal center. The Ti-N(amine) bond is longer than the Ti-N(anilide) bond by about 0.29 Å. The two ligands are arranged trans to each other and the mol-ec...

In the title coordination polymer, [HgCl(2)(C(11)H(9)N(3))](n), the Hg(II) ion is coordinated by three N atoms from two N-[(E)-pyridin-2-yl-methyl-idene]pyridin-3-amine (L) ligands and two chloride anions in a distorted trigonal-bipyramidal geometry. The two pyridine rings in L form a dihedral angle of 50.0 (2)°. L ligands bridge adjacent HgCl(2) units into polymeric chains propagating in [010]...

Reactivities of non-heme iron(IV)-oxo complexes are mostly controlled by the ligands. Complexes with tetradentate ligands such as [(TPA)FeO]2+ (TPA=tris(2-pyridylmethyl)amine) belong to most reactive ones. Here, we show a fine-tuning reactivity an additional ligand X (X=CH3CN, CF3SO3?, ArI, and ArIO; ArI=2-(tBuSO2)C6H4I) attached in solution reveal thus far unknown role ArIO oxidant. The HAT [(...

Abstract This work probes the potential of fluorous fatty acids as stabilizing ligands in synthesis mixed halide perovskite quantum dots (MHP QDs). Traditionally, MHP QDs are synthesized presence oleic acid (OA) and oleyl amine (OAm). Here have been used along with OA OAm to yield higher stability. Increased fractions molecules reaction mixture require process be carried out at a temperature du...

The mononuclear Ni(II) amide, [Ni(C(12)H(21)N(2)Si)(2)], has the Ni(II) atom N,N'-chelated by the N-silylated anilinide ligands. The ligands are arranged cis to each other and obey the C(2)-symmetry operation. The two ends of the N-Si-N chelating unit exhibit different affinities for the metal atom: the Ni-N(anilinide) bond length is 1.913 (3) Å and Ni-N(amine) is 2.187 (3) Å. The four-coordina...

Herein, we report theoretical evidence of the geometric changes occurring upon complexation, for a series of octupolar bipyrimidine-based ligands incorporating the NPh2 terminal donor group. It is shown that ligands 1 and 2 (4,4',6,6'-tetrakis(N,N-diphenylaminostyryl)-[2,2']bipyrimidine and 4,4',6,6'-tetrakis((N,N-diphenyl)-9,9'-dioctyl-9H-fluorene-2-amine)-2,2'-bipyrimidine) exhibit a non-plan...

The zinc complexes [(L1)(2)Zn(MeOH)(2)](OTf)(2), [(L1)ZnCl(2)], [(L2)ZnCl(2)], [(L2)Zn(OTf)(H(2)O)]OTf and [(Me-bispic)ZnCl(2)] of the ligands N-[(2-pyridyl)methyl]-2,2'-dipyridylamine (L1), N-[bis(2-pyridyl)methyl]-2-pyridylamine (L2) and N-methyl-[bis(2-pyridyl)methyl]amine (Me-bispic) were synthesised and characterised. The first copper(I) complexes of the ligands L1 and L2 were also synthes...

In the conventional procedure of the preparation of aqueous semiconductor nanocrystals (NCs), the growth of NCs was mainly through the thermodynamics-favored Ostwald ripening process. It required additional energy to promote NC growth, such as reflux, hydrothermal method, microwave irradiation, and sonochemical synthesis. Energy-promoted growth usually led to the decomposition of mercapto-ligan...

Recent studies suggest that the second extracellular loop (o2 loop) of bovine rhodopsin and other class I G protein-coupled receptors (GPCRs) targeted by biogenic amine ligands folds deeply into the transmembrane receptor core where the binding of cis-retinal and biogenic amine ligands is known to occur. In the past, the potential role of the o2 loop in agonist-dependent activation of biogenic ...
