Diiodido[4'-(4-pyrid-yl)-2,2':6',2''-terpyridine-?N,N',N'']copper(II).

ABSTRACT: The Cu(II) atom in the title compound, [CuI(2)(C(20)H(14)N(4))], has a distorted square-pyramidal coordination formed by the N atoms of the tridentate 4'-(4-pyrid-yl)-2,2':6'2''-terpyridine (pyterpy) ligand and two I atoms; one of the I atoms is in the apical position. In contrast to other known square-pyramidal diiodido- and dibromidocopper complexes of the pyterpy ligand in which metal-halogen distances are significantly different, in the title compound the apical and equatorial Cu-I bonds are almost identical [2.6141?(8) and 2.6025?(8)?Å, respectively].

Poly[?(2)-chlorido-dichlorido[?(2)-4'-(4-pyrid-yl)-2,2':6',2''-terpyridine]-copper(I)copper(II)].

Project description:In the mixed-valence Cu(I)/Cu(II) coordination polymer, [Cu(2)Cl(3)(C(20)H(14)N(4))](n), the two Cu atoms are bridged to a pair of Cl atoms across a centre of inversion. The monovalent metal atoms is coordinated by a pyridine N atom as well as by three Cl atoms in a tetra-hedral CuNCl(3) geometry. The divalent metal atom is N,N',N''-chelated by the heterocycle, and it exists in a square-pyramidal CuN(3)Cl(2) geometry; the apical site is occupied by the second bridging Cl atom. The bridging modes of the Cl atoms and the heterocycle give rise to the formation of a layered arrangement parallel to (001).

?-Adipato-bis-[chlorido(2,2':6',2''-terpyridine)-copper(II)] tetra-hydrate.

Project description:In the title compound, [Cu(2)(C(6)H(8)O(4))Cl(2)(C(15)H(11)N(3))(2)]·4H(2)O, the dinuclear copper complex is located on a crystallographic inversion centre. Each Cu atom is in a distorted square-pyramidal coordination environment, with one O atom of an adipate dianion and three N atoms from the 2,2':6',2''-terpyridine ligand occupying the basal plane, and one chlorine in the apical site. In addition, there is weak Cu-O inter-action opposite of the chlorine with a distance of 2.768?(1)?Å. The adipate ligand adopts a gauche-anti-gauche conformation. The inter-stitial water mol-ecules form hydrogen-bonded tertramers that are connected to the complexes via O-H?O and O-H?Cl hydrogen bonds, thus leading to the formation of tightly hydrogen-bonded layers extending perpendicular to the b-axis direction.

?-Succinato-bis-[aqua-(2,2':6',2''-terpyridine)copper(II)] dinitrate dihydrate.

Project description:The title compound, [Cu(2)(C(4)H(4)O(4))(C(15)H(11)N(3))(2)(H(2)O)(2)](NO(3))(2)·2H(2)O, was synthesized under hydro-thermal conditions. The dinuclear copper complex is located on a crystallographic inversion centre. The Cu(II) ion is penta-coordinated in a tetra-gonal-pyramidal geometry, with one O atom of a succinate dianion and three N atoms of a 2,2':6',2''-terpyridine ligand occupying the basal plane, and a water O atom located at the apical site. In the crystal structure, O-H?O hydrogen bonding links the mol-ecules into a chain parallel to the a axis.

Project description:The title compound, [Zn(CH(3))(2)(C(15)H(11)N(3))], was synthesized by the addition of dimethyl-zinc to 2,2':6',2''-terpyridine and was crystallized by the slow evaporation of THF. The penta-coordinate Zn(II) atom, lying on a twofold rotation axis, displays a distorted trigonal-bipyramidal geometry, with two terminal N atoms at the axial positions and the central N atom and two methyl C atoms at the equatorial positions.

[4'-(2-Bromo-5-pyrid-yl)-2,2':6',2''-terpyridine-κN,N',N'']bis(triphenyl-phosphine-κP)-copper(I) tetra-fluorido-borate dichloro-methane hemisolvate.

Project description:In the title complex, [Cu(C(20)H(13)BrN(4))(C(18)H(15)P)(2)]BF(4)·0.5CH(2)Cl(2), the copper(I) cation adopts a distorted tetra-hedral arrangement, coordinated by two triphenyl-phosphine ligands and two N atoms of the potentially tridentate terpyridine ligand. One half-mol-ecule of dichloro-methane crystallizes with the complex. The chlorine atoms are disordered over two sites with occupancies fixed at 0.30 and 0.20 respectively.

[4'-(4-Amino-phen-yl)-2,2':6',2''-terpyridine]-chloridopalladium(II) chloride.

Project description:The Pd(II) atom in the complex cation of the title compound, [PdCl(C(21)H(16)N(4))]Cl, is coordinated by three N atoms derived from the terpyridine ligand and a chloride ion, which define a distorted PdClN(3) square-planar coordination geometry. In the crystal, the presence of N-H?Cl hydrogen bonds involving the amino H atom and chloride anions link two cations and two anions into a four-ion aggregate via centrosymmetric eight-membered [?H-N-H?Cl](2) synthons. Layers of cations are inter-spersed with the chloride anions with stabilization provided by C-H?Cl inter-actions involving both Cl atoms, as well as ?-? inter-actions [the closest inter-action of 3.489?(6)?Å occurs between a chelate ring and a pyridyl residue].

N-(6-{2-[6-(2,2-Dimethyl-propanamido)-2-pyrid-yl]eth-yl}-2-pyrid-yl)-2,2-dimethyl-propanamide.

Project description:The title compound, C(22)H(30)N(4)O(2), lies about a crystallographic inversion center. The whole mol-ecule is disordered over two positions with a refined occupancy ratio of 0.636?(10):0.364?(10). The pyridine rings are approximately planar, with maximum deviations of 0.033?(10) and 0.063?(17)?Å for the major and minor components, respectively. The mean planes of the pyridine rings form dihedral angles of 17?(2)° in the major component and 18?(2)° in the minor component with the respective formamide groups attached to them. In the crystal packing, inter-molecular N-H?O and C-H?O hydrogen bonds link the mol-ecules into two-dimensional networks parallel to the ab plane.

Aqua-[2-(2-pyrid-yl)-1,8-naphthyridine-?N,N](2,2':6',2''-terpyridine-?N,N',N'')ruthenium(II) bis-(hexa-fluorido-phosphate) acetone sesquisolvate.

Project description:The asymmetric unit of the title compound, [Ru(C(13)H(9)N(3))(C(15)H(11)N(3))(H(2)O)](PF(6))(2)·1.5C(3)H(6)O, consists of two crystallographically independent Ru(II) complexes. Each complex is approximately octa-hedral with the Ru(II) atom bound by an N,N'-coordinated 2-(2-pyrid-yl)-1,8-naphthyridine (pynp) ligand, a meridional 2,2':6',2''-terpyridine (tpy) ligand and one aqua ligand. The tpy ligand is coordinated in a planar tridentate fashion with the central N atom closest to the Ru(II) atom. The aqua ligand is trans to the pyridine N atom of pynp. The long Ru-O distances [2.150?(5) and 2.138?(5)?Å] are typical for aqua ligands in polypyridyl ruthenium complexes. In the crystal, both intra-molecular O-H?N and inter-molecular O-H?O hydrogen bonds are observed.
