(2-Hydroxy-benzoato-?O)[tris-(1-methyl-benzimidazol-2-ylmethyl-?N)amine-?N]cobalt(II) perchlorate dimethyl-formamide sesquisolvate.

ABSTRACT: In the title complex, [Co(C(7)H(5)O(3))(C(27)H(27)N(7))]ClO(4)·1.5C(3)H(7)NO, the Co(II) ion is five-coordinated by four N atoms from a tris-(N-methyl-benzimidazol-2-ylmeth-yl)amine (Mentb) ligand and one O atom from a salicylate ligand in a distorted trigonal-bipyramidal geometry with approximate mol-ecular C(3) symmetry. The perchlorate ion is disordered over two sites with equal occupancy. One dimethyl-formamide solvent 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. There is an intra-molecular O-H?O hydrogen bond in the cation.

Project description:In the title complex, [Mn(C(7)H(5)O(3))(C(27)H(27)N(7))(C(3)H(7)NO)]ClO(4)·C(3)H(7)NO, the Mn(II) ion is coordinated in a slightly distorted monocapped trigonal-prismatic geometry. The tris-(1-methyl-1H-benzimidazol-2-ylmeth-yl)amine (Mentb) ligand coordinates in a tetra-dentate mode and the coordination is completed by a bis-chelating salicylate ligand and a dimethyl-formamide ligand. The hy-droxy group and the ortho H atoms of the salicylate ligand were refined as disordered over two sites with occupancies of 0.581 (8) and 0.419 (8). Both disorder components of the hy-droxy group form intra-molecular O-H⋯O hydrogen bonds.

Acrylato[tris-(1-methyl-1H-benzimidazol-2-ylmeth-yl)amine]cobalt(II) perchlorate-dimethyl-formamide-methanol (2/2/3).

Project description:In the title complex, [Co(C(3)H(3)O(2))(C(27)H(27)N(7))]ClO(4)·C(3)H(7)NO·1.5CH(4)O, the Co(II) ion is five-coordinated by four N atoms from a tris-(1-methyl-1H-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 0.90 and 0.10. In addition, the solvent hemimethanol mol-ecule is disordered over two positions with equal occupancies. The crystal structure is stabilized by weak intermolecular O-H⋯O hydrogen bonds.

Bis[(2-methyl-benz-yl)bis-(pyridin-2-ylmethyl-κN)amine-κN]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).

(Acetonitrile){2-[bis-(pyridin-2-ylmethyl-κ(2)N)amino-κN]-N-(2,6-dimethyl-phen-yl)acetamide-κO}(perchlorato-κO)zinc (acetonitrile){2-[bis-(pyridin-2-ylmethyl-κ(2)N)amino-κN]-N-(2,6-dimethyl-phen-yl)acetamide-κO}zinc tris-(perchlorate).

Project description:In the title salt, [Zn(C(22)H(24)N(4)O)(CH(3)CN)][Zn(ClO(4))(C(22)H(24)N(4)O)(CH(3)CN)](ClO(4))(3), two differently coordinated zinc cations occur. In the first complex, the metal ion is coordinated by the N,N',N'',O-tetra-dentate acetamide ligand and an acetonitrile N atom, generating an approximate trigonal-bipyramidal coordination geometry, with the O atom in an equatorial site and the acetonitrile N atom in an axial site. In the second complex ion, a perchlorate ion is also bonded to the zinc ion, generating a distorted trans-ZnO(2)N(4) octa-hedron. Of the uncoordinating perchlorate ions, one lies on a crystallographic twofold axis and one lies close to a twofold axis and has a site occupancy of 0.5. N-H⋯O and N-H⋯(O,O) hydrogen bonds are observed in the crystal. Disordered solvent mol-ecules occupy about 11% of the unit-cell volume; their contribution to the scattering was removed with the SQUEEZE routine of the PLATON program [Spek (2009 ▶). Acta Cryst. D65, 148-155.].

Project description:The title complex, [Ca(C(27)H(30)N(4)O(3))(2)](ClO(4))(2)·2CH(3)CN, is composed of centrosymmetric (CaL(2))(2+) cations [L = tris-(2-hy-droxy-benzoyl-amino-eth-yl)amine = H(3)saltren], uncoordin-ated perchlorate anions and acetonitrile solvent mol-ecules. The calcium ion is six-coordinated and is bonded to all phen-oxy O atoms from both zwitterionic saltren mol-ecules. There are strong intra-molecular N-H⋯O hydrogen bonds. The cations are linked into chains via weak inter-molecular C-H⋯O hydrogen bonds and C-H⋯π and π-π stacking inter-actions [centroid-centroid distances = 3.306 (3) and 3.415 (3) Å].

(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.
