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

ABSTRACT: 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).

(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.

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

Project description: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.

[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[(2-methyl-benz-yl)bis-(pyridin-2-ylmethyl-?N)amine-?N]manganese(II) bis-(perchlorate).

Project description:In the title complex, [Mn(C20H21N3)2](ClO4)2, two tridentate (2-methyl-benz-yl)bis-(pyridin-2-ylmeth-yl)amine (L) ligands form the Mn(II) complex [MnL 2](ClO4)2. The Mn(II) ion lies on a twofold axis and the complex cation is significantly distorted from regular octa-hedral geometry. The packing is stabilized by weak C-H?O inter-actions between the cations and anions, which link them into a zigzag ribbon along [101]. The perchlorate anion is disordered and was constrained to be tetra-hedral with two orientations having occupancies of 0.768?(4) and 0.232?(4). The 2-methylbenzyl moiety is also disordered over two sets of sites, with occupancies of 0.508?(15) and 0.492?(15).

catena-Poly[[[(dimethyl-malonato-?O:O')(perchlorato-?O)copper(II)]-?-bis-(3-pyridylmeth-yl)piperazinediium-?N:N] perchlorate dihydrate].

Project description:In the title compound, {[Cu(C(5)H(6)O(4))(ClO(4))(C(16)H(22)N(4))]ClO(4)·2H(2)O}(n), square-pyramidally coordinated Cu atoms with perchlorate and dimethyl-malonate ligands are connected into cationic sinusoidal coordination polymer chains by doubly protonated bis-(3-pyridylmeth-yl)piperazine (3-bpmp) ligands. The chains aggregate into pseudo-layers parallel to the (101) crystal planes by N-H?O hydrogen bonding. Unligated perchlorate anions and water mol-ecules of crystallization provide additional hydrogen bonding between pseudo-layers.

(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.

Diaqua-sodium(I) perchlorate bis-[?-2-(carboxyl-atomethyl-imino-meth-yl)phenolato]bis-[(3-methyl-pyridine)copper(II)].

Project description:In the title compound, [Na(H(2)O)(2)]ClO(4)·[Cu(2)(C(9)H(7)NO(3))(2)(C(6)H(7)N)(2)], the Cu(II) atom is coordinated by one N atom and two O atoms from a tridentate N-salicylideneglycinate Schiff base dianion and one N atom from a 3-methyl-pyridine ligand. Longer Cu?O contacts [2.680?(2)?Å] complete an approximate square-based pyramidal coordination geometry around Cu(II), forming a dimeric complex across a centre of inversion. The dimeric complexes form stacks along the a axis, with Cu?O contacts of 3.332?(2)?Å between them. The Na(+) cations and perchlorate anions lie on twofold rotation axes between the stacks. The former are coordinated by two disordered water mol-ecules (each with half-occupancy), and form Na?O contacts of 3.698?(3)?Å to the perchlorate anions and Na?? contacts to neighbouring salicylideneglycinate ligands [shortest Na?C = 3.516?(3)?Å].

Crystal structure of μ-oxalodi-hydroxamato-bis-[(2,2'-bipyrid-yl)(di-methyl sulfoxide-κO)copper(II)] bis-(perchlorate).

Project description:The centrosymmetric binuclear complex, [Cu2(C2H2N2O4)(C10H8N2)2(C2H6OS)2](ClO4)2, contains two copper(II) ions, connected through an N-deprotonated oxalodi-hydroxamic acid dianion, two terminal 2,2'-bi-pyridine ligands, and two apically coordinating dimethylsulfoxide mol-ecules. Two non-coordinating perchlorate anions assure electrical neutrality. The copper(II) ions in the complex dication [Cu2(C10H8N2)2(μ-C2H2N2O4)(C2H6SO)2](2+) are in an O2N3 square-pyramidal donor environment, the Cu-Cu separation being 5.2949 (4) Å. Two hydroxamate groups in the deprotonated oxalodi-hydroxamic acid are located trans to one each other. In the crystal, O-H⋯O and C-H⋯O hydrogen bonds link the complex cations to the perchlorate anions. Further C-H⋯O hydrogen bonds combine with π-π contacts with a centroid-to-centroid separation of 3.6371 (12) Å to stack the mol-ecules along the a-axis direction.

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).
