(Dicyanamido)[tris-(2-pyridylmeth-yl)amine]zinc(II) perchlorate.

ABSTRACT: In the title complex, [Zn(C(2)N(3))(C(18)H(18)N(4))]ClO(4), the Zn(II) ion has a slightly distorted trigonal-bipyramidal ZnN(5) coordination geometry. The crystal structure is stabilized by weak inter-molecular C-H?O and C-H?N hydrogen bonds. In addition, there are relatively close contacts between the O atoms of the perchlorate anion and symmetry-related pyridine rings [O?Cg = 3.179?(3) and 3.236?(3)?Å, where Cg is the centroid of a pyridine ring], and between the terminal N atom of the dicyanamide ligand and pyridine rings [N?Cg = 3.381?(4)-3.761?(3)?Å]. The central N atom of the dicyanamide ligand is disordered over two sites in an approximately 0.6:0.4 ratio.

In the title complex, [Zn(C(2)N(3))(C(18)H(18)N(4))]ClO(4), the Zn(II) ion has a slightly distorted trigonal-bipyramidal ZnN(5) coordination geometry. The crystal structure is stabilized by weak inter-molecular C-H⋯O and C-H⋯N hydrogen bonds. In addition, there are relatively close contacts between the O atoms of the perchlorate anion and symmetry-related pyridine rings [O⋯Cg = 3.179 (3) and 3.236 (3) Å, where Cg is the centroid of a pyridine ring], and between the terminal N atom of the dicyana ...[more]

[(6-Methyl-2-pyridylmeth-yl)(2-pyridylmeth-yl)amine][(2-pyridylmeth-yl)amine]copper(II) bis-(perchlorate).

Project description:The title compound, [Cu(C(6)H(8)N(2))(C(13)H(15)N(3))](ClO(4))(2), is a mixed ligand complex with the Cu(II) atom coordinated by (6-methyl-2-pyridylmeth-yl)(2-pyridylmeth-yl)amine, acting as a tridentate ligand, and 2-(2-amino-meth-yl)pyridine, as a bidentate ligand, leading to an N(5) square-pyramidal geometry. The amine H atoms are involved in hydrogen bonding to the perchlorate O atoms and there are extensive but weak inter-molecular C-H⋯O inter-actions in the crystal structure. The perchlorate ions are each disordered over two positions, with site occupancies of 0.601 (8):0.399 (8) and 0.659 (11):0.341 (11).

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.

[Bis(2-pyridylmeth-yl)amine]dichloridomercury(II).

Project description:The Hg atom in the title complex, [HgCl(2)(C(12)H(13)N(3))], adopts a square-pyramidal geometry, being ligated by three N atoms of the tridentate bis-(2-pyridylmeth-yl)amine ligand and two Cl atoms, with one of the latter occupying the apical position. Disorder is noted in the amine portion of the ligand and this was modelled over two sites, with the major component having a site-occupancy factor of 0.794 (14).

Bis(thio-cyanato-?N)[tris-(2-pyridylmeth-yl)amine-?N,N',N'',N''']nickel(II) methanol hemisolvate.

Project description:The title complex, [Ni(NCS)(2)(C(18)H(18)N(4))]·0.5CH(3)OH, consists of two crystallographically distinct complexes and a methanol solvent mol-ecule. The Ni(II) complexes are pseudo-octa-hedral six-coordinate, with the tris-(2-pyridylmeth-yl)amine (TPA) ligand providing four N atoms and two N-bound thio-cyanates providing the final two N atoms. The distances and angles are typical for Ni(II)-TPA complexes. The compound has unit-cell parameters that are surprisingly similar to the previously reported hydrate.

Di-?-chlorido-bis-{[2-({[2-(2-pyrid-yl)eth-yl](2-pyridylmeth-yl)amino}meth-yl)phenol]zinc(II)} bis-(perchlorate) dihydrate.

Project description:The title compound, [Zn(2)Cl(2)(C(20)H(21)N(3)O)(2)](ClO(4))(2)·2H(2)O, consists of a dinuclear Zn(II) cationic complex, two disordered perchlorate anions and two water mol-ecules as solvate. The [Zn(2)(?-Cl)(2)(HL)(2)](2+ )cation [HL is 2-({[2-(2-pyrid-yl)eth-yl](2-pyridylmeth-yl)amino}meth-yl)phenol] has a centrosymmetric structure with the Zn(II) ions in a distorted octa-hedral environment surrounded by an N(3)OCl(2) donor set. HL acts as a tetra-dentate ligand through three N atoms from one amine group and two pyridyl arms and one O atom from the phenolic arm. The three N-donor sites of the HL ligand are arranged in meridional fashion, with the pyridine rings coordinated in trans positions with respect to each other. Consequently, the amine and phenol groups are trans to the asymmetric di-?-chlorido exogenous bridges. A polymeric chain is formed along [010] by C(12)R(4) (2)(8) inter-molecular hydrogen bonding. The perchlorate anion is disordered and was modelled by two sites in a 0.345?(18):0.655?(18) ratio. Water-perchlorate O-H?O inter-actions form cyclic structures, while phenol-water O-H?O inter-actions generate an infinite chain. In addition, weak inter-molecular C-H??(Ph) inter-actions between pyridine donor and phenol acceptor groups of neighboring cations build a two-dimensional polymeric structure parallel to (110).

Acrylato[tris-(1-methyl-benzimidazol-2-ylmeth-yl)amine]zinc(II) perchlorate-dimethyl-formamide-methanol (1/1/1.5) at 153 (2) K.

Project description:In the title complex, [Zn(C(3)H(3)O(2))(C(27)H(27)N(7))](ClO(4))·C(3)H(7)NO·1.5CH(4)O, the Zn(II) ion is five-coordinated by four N atoms from a tris-(1-methyl-benzimidazol-2-ylmeth-yl)amine (Mentb) ligand and one O atom from an acrylate ligand in a distorted trigonal-bipyramidal geometry with approximate mol-ecular C(3) symmetry. The atoms of the acrylate ligand are disordered over two sites, with approximate occupancies of 0.84 and 0.16. In addition, a methanol solvent mol-ecule is disordered over two sites with equal occupancies. In the crystal structure, the full-occupancy methanol is linked to a dimethyl-formamide mol-ecule by an inter-molecular O-H⋯O hydrogen bond.

μ-Oxido-bis-{chlorido[tris-(2-pyridylmeth-yl)amine]chromium(III)} bis(hexafluoridophosphate).

Project description:The title compound, [Cr(2)Cl(2)O(C(18)H(18)N(4))(2)](PF(6))(2), is isostructural with the V(III) analogue. Each Cr(III) atom is chelated by the tetra-dentate tris-(2-pyridylmeth-yl)amine ligand via four N atoms, and further coordinated by one Cl atom and one bridging O atom, giving a slightly distorted octa-hedral coordination geometry. The dinuclear complex is centrosymmetric, with the bridging O atom lying on a centre of inversion.

Bis(dicyanamido-κN)[tris-(3-amino-propyl)amine-κ(4) N]nickel(II).

Project description:In the title complex, [Ni(C2N3)2(C9H24N4)], the Ni(II) atom is coordinated in a distorted octa-hedral geometry by one tris-(3-amino-prop-yl)amine (tris-apa) ligand and two dicyanamide (dca) ligands [one of them disordered in a 0.681 (19):0319 (19) ratio]. Inter-molecular N-H⋯N hydrogen bonds involving the N atoms of the dca anions and the tris-apa amine H atoms result in the formation of a three-dimensional network.

(Acetonitrile)[bis-(2-pyridylmeth-yl)amine]bis-(perchlorato)copper(II).

Project description:In the title compound, [Cu(ClO(4))(2)(C(12)H(13)N(3))(C(2)H(3)N)], the Cu(II) atom is six-coordinate in a Jahn-Teller distorted octahedral geometry, with coordination by the tridentate chelating ligand, an acetonitrile mol-ecule, and two axial perchlorate anions. The tridentate ligand bis-(2-pyridylmeth-yl)amine chelates meridionally and equatorially while an acetonitrile mol-ecule is coordinated at the fourth equatorial site. The two perchlorate anions are disordered with site occupancy factors of 0.72/0.28. The amine H is involved in intra-molecular hydrogen bonding to the perchlorate O atoms and there are extensive but weak inter-molecular C-H⋯O inter-actions.
