Crystal structure of [tris-(pyridin-2-ylmeth-yl)amine-?(4) N]copper(II) bromide.

ABSTRACT: In the asymmetric unit of the title compound, [CuBr(C18H18N4)]Br, there are three crystallographically independent cations. One of the cations exhibits positional disorder of the pyridin-2-yl-methyl groups over two sets of sites with refined occupancies of 0.672?(8) and 0.328?(8). The outer-sphere bromine counter-ion is severely disordered over multiple sites. In each cation, the Cu(II) ion is coordinated by the four N atoms of the tris-(pyridin-2-ylmeth-yl)amine ligand and one bromine and adopts a slightly distorted trigonal-bipyramidal geometry.

Crystal structure of a seven-coordinate manganese(II) complex with tris-(pyridin-2-ylmeth-yl)amine (TMPA).

Project description:Structural analysis of (acetato-?2O,O')(methanol-?O)[tris-(pyridin-2-ylmeth-yl)amine-?4N,N',N'',N''']manganese(II) tetraphenyl-borate, [Mn(C2H3O2)(C18H18N4)(CH3OH)](C24H20B) or [Mn(TMPA)(Ac)(CH3OH)]BPh4 [TMPA = tris-(pyridin-2-ylmeth-yl)amine, Ac = acetate, BPh4 = tetra-phenyl-borate] by single-crystal X-ray diffraction reveals a complex cation with tetra-dentate coordination of the tripodal TMPA ligand, bidentate coordination of the Ac ligand and monodentate coordination of the methanol ligand to a single MnII center, balanced in charge by the presence of a tetra-phenyl-borate anion. The MnII complex has a distorted penta-gonal-bipyramidal geometry, in which the central amine nitro-gen and two pyridyl N atoms of the TMPA ligand, and two oxygen atoms of the acetate ligand occupy positions in the penta-gonal plane, while the third pyridyl nitro-gen of TMPA and the oxygen from the methanol ligand occupy the axial positions. Within the complex, the acetate O atoms participate in weak C-H?O hydrogen-bonding inter-actions with neighboring pyridyl moieties. In the crystal, complexes form dimers by pairs of O-H?O hydrogen bonds between the coordinated methanol of one complex and an acetate oxygen of the other, and weak ?-stacking inter-actions between pyridine rings. Separate dimers then undergo additional ?-stacking inter-actions between the pyridine rings of one moiety and either the pyridine or phenyl rings of another moiety that further stabilize the crystal.

(Salicylato)[tris-(1-methyl-1H-benz-imidazol-2-ylmeth-yl)amine]copper(II) perchlorate dimethyl-formamide disolvate.

Project description:In the title complex, [Cu(C(7)H(5)O(3))(C(27)H(27)N(7))]ClO(4)·2C(3)H(7)NO, the Cu(II) ion is five-coordinated by four N atoms from the tris-(1-methyl-1H-benzimidazol-2-ylmeth-yl)amine ligand and an O atom of the monodentate salicylate ligand. The N(4)O donor set defines a coordination geometry inter-mediate between square-pyramidal and trigonal-bipyramidal. The crystal structure is stabilized by O-H⋯O inter-actions. The atoms of the aromatic ring of the salicylate ligand are disordered over two sites of equal occupancy. In addition, one of the dimethyl-formamide solvent mol-ecules is partially disordered over two positions, of approximately equal occupancy.

Crystal structure and characterization of a new copper(II) chloride dimer with meth-yl(pyridin-2-yl-methyl-idene)amine.

Project description:The new copper(II) complex, namely, di-?-chlorido-bis-{chlorido-[meth-yl(pyri-din-2-yl-methyl-idene)amine-?2 N,N']copper(II)}, [Cu2Cl4(C7H8N2)2], (I), with the ligand 2-pyridyl-methyl-N-methyl-imine (L, a product of Schiff base condensation between methyl-amine and 2-pyridine-carbaldehyde) is built of discrete centrosymmetric dimers. The coordination about the CuII ion can be described as distorted square pyramidal. The base of the pyramid consists of two nitro-gen atoms from the bidentate chelate L [Cu-N = 2.0241?(9), 2.0374?(8)?Å] and two chlorine atoms [Cu-Cl = 2.2500?(3), 2.2835?(3)?Å]. The apical position is occupied by another Cl atom with the apical bond being significantly elongated at 2.6112?(3)?Å. The trans angles of the base are 155.16?(3) and 173.79?(2)°. The Cu?Cu separation in the dimer is 3.4346?(3)?Å. In the crystal structure, the loosely packed dimers are arranged in stacks propagating along the a axis. The X-band polycrystalline 77?K EPR spectrum of (I) demonstrates a typical axial pattern characteristic of mononuclear CuII complexes. Compound (I) is redox active and shows a cyclic voltammetric response with E 1/2 = -0.037?V versus silver-silver chloride electrode (SSCE) assignable to the reduction peak of CuII/CuI in methanol as solvent.

[Bis(pyridin-2-ylmeth-yl)amine-κ(3)N,N',N'']tricarbonyl-rhenium(I) bromide hemihydrate.

Project description:The title compound, fac-[Re(C(12)H(12)N(3))(CO)(3)]Br·0.5H(2)O, crystallizes with a cationic rhenium(I) unit, a bromide ion and half a water mol-ecule, situated on a twofold rotation axis, in the asymmetric unit. The Re(I) atom is facially surrounded by three carbonyl ligands and a tridentate bis-(pyridin-2-ylmeth-yl)amine ligand in a distorted octahedral environment. N-H⋯Br, O-H⋯Br, C-H⋯O and C-H⋯Br hydrogen bonds are present in the crystal structure and π-π stacking is also observed [centroid-centroid distances = 3.669 (1) Å and 4.054 (1) Å], giving rise to a three-dimentional network. The mol-ecules pack in a head-to-head fashion along the ac plane.

Crystal structure of tris-[4-(naphthalen-1-yl)phen-yl]amine.

Project description:In the title mol-ecule, C48H33N, the central N atom shows no pyramidalization, so that the N atom and the three C atoms bound to the N atom lie almost in the same plane. The three para-phenyl-ene rings bonded to the N atom are in a propeller form. All of the naphthalene ring systems are slightly bent. In the crystal, mol-ecules form an inversion dimer, through two pairs of C-H⋯π inter-actions, which further inter-acts with the adjacent dimer via another two pairs of C-H⋯π inter-actions, forming a column structure along the a axis. There are no significant inter-actions between these column structures.

Salicylato[tris-(N-methyl-benzimidazol-2-ylmeth-yl)amine]zinc(II) perchlorate dimethyl-formamide sesquisolvate.

Project description:In the title complex, [Zn(C(7)H(5)O(3))(C(27)H(27)N(7))]ClO(4)·1.5C(3)H(7)NO, the Zn(II) atom is five-coordinated by four N atoms from a tris-(N-methyl-benzimidazol-2-ylmeth-yl)amine ligand and one O atom from a salicylate ligand in a distorted trigonal-bipyramidal geometry (τ parameter = 0.84), with approximate mol-ecular C(3) symmetry. One dimethyl-formamide mol-ecule lies on a general position and is disordered over two coplanar orientations with equal occupancy. A second dimethyl-formamide mol-ecule is disordered about a twofold rotation axis.

Crystal structure of <i>catena</i>-poly[[(μ-6-{[bis-(pyridin-2-ylmeth-yl)amino]-meth-yl}pyridine-2-carboxyl-ato)copper(II)] perchlorate aceto-nitrile monosolvate].

Project description:The crystal structure of the title compound, {[Cu(C19H17N4O2)]ClO4·C2H3N} n , is reported and compared to similar structures in the literature. The compound crystallizes in the monoclinic space group P21. The unit cell contains one complex mol-ecule in addition to perchlorate as the counter-ion and solvent (aceto-nitrile). The crystal packing evinces extended chains whereby the carboxyl-ate moiety on the 6-carboxyl-ato-2-(pyridyl-meth-yl)bis-(pyridin-2-ylmeth-yl)amine ligand bridges between two different copper centers in adjacent mol-ecules. This packing arrangement for the title compound appears to be unique when compared to allied structures in the literature. The perchlorate anion showed signs of disorder and its oxygen atoms were modelled over two sets of partially occupied sites, the occupancy of which was competitively refined to 0.564 (12)/0.436 (12). The crystal studied was refined as a two-component inversion twin.
