METAL COMPLEXES FOR PROMOTING GROWTH IN A PHOTOSYNTHETIC ORGANISM
-
Paragraph 0190; 0192, (2020/05/28)
A method of promoting growth in a photosynthetic organism comprising treating the photosynthetic organism with a metal complex or a precursor thereof, wherein the metal complex comprises a metal selected from the group consisting of zinc (Zn), cobalt (Co), copper (Cu), nickel (Ni) and iron (Fe), and a ligand, which is a bidentate or tridentate ligand. Metal complexes and their ligands are also described.

Page/Page column 22; sheet 1, (2009/04/25)
Ligands useful for promoting copper-catalyzed azide-alkyne cycloaddition reactions comprise a compound represented by structural Formula (I) as described in the specification, wherein in Formula (I) Z1 is a nitrogen-containing heterocyclic group or a group represented by the formula : Y1-(CH2)c-Y2-(CH2)d-Y3-CH2-N(CH2Z4)(CH2Z5), where Y1 is -E1-C(O)O-, -E1-C(O)NH-, -E1-, or a covalent bond; Y2 is a covalent bond, -CH=CH-, or a 1,4-(1,2,3-triazolyl) group; Y3 is -OC(O)-E2-, -NHC(O)-E2-, -E2-, or a covalent bond; each of E1 and E2 is a benzimidazolyl group attached at the 1 and 2 positions; each of c and d is independently 1, 2, 3, 4, or 5; each of Z2, Z3, Z4 and Z5 is a nitrogen-containing heterocyclic group including a substituent X1 and optionally including a substituent (CH2)n-R1, and Y1, Y2, Y3, X1, R1, c, d and n are each as defined in the specification.

A series of copper(II) complexes of the title ligand are reported which exhibit both five-coordinate trigonal bipyramidal and pseudo-octahedral stereochemistries.Mixed stereochemistry complexes 2 (X=Cl, Br), 2*CH3CN, and the complexes BPh4(CH3CN)2*0.5H2O, NO3*0.5H2O, contain trigonal bipyramidal cations while six-coordinate structure are implicated in the systems *H2O and (ClO4)2*MeOH*H2O.The molecular structure of NO3*0.5H2O has been determined by single crystal X-ray diffractometry.The crystal is monoclinic and belongs to the space group C2/c with Z=8, a=24.254(3), b=14.107(2), c=16.329(2) Angstroem and β=105.94(1) degree.The complex adopts a distorted trigonal bipyramidal structure (no axial symmetry) with the ligand coordinating in a 'tripod' fashion as an N4 donor.The fifth ligand is a monodentate nitrate.The mean Cu-N distance is 2.07(3) Angstroem and the Cu-O distance is 1.938(3) Angstroem.A second nitrate oxygen atom is close to the copper centre (Cu-O distance 2.783(4) Angstroem) and may represent a weakly bound sixth ligand.Both infrared and electronic spectral data support the presence of a sixth ligand.Both infrared and electronic spectral data support the presence of a sixth ligand.
