(Dimethyl-formamide-?O)(2-hy-droxy-benzoato-?O,O)[tris-(1-methyl-1H-benzimidazol-2-ylmethyl-?N)amine-?N]manganese(II) perchlorate dimethyl-formamide monosolvate.

ABSTRACT: 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.

Project description: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 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.].

Dichlorido(dimethyl-formamide-κO)[1,4,7-tris-(2-cyano-ethyl)-1,4,7-triaza-cyclo-nonane-κN,N,N]cobalt(II).

Project description:The title compound, [CoCl(2)(C(15)H(24)N(6))(C(3)H(7)NO)], crystallizes as a monomeric complex. The coordination environment around the Co(II) center could be described as a distorted octa-hedron consisting of three N donors from the facially coordinating triaza macrocyclic ligand, one O donor from dimethyl-formamide and two Cl(-) ions. Neutral complex mol-ecules are associated via inter-molecular C-H⋯Cl hydrogen bonds to form two-dimensional layers. C-H⋯O hydrogen bonds are also present.

catena-Poly[[(diiodidocadmium)-μ-{1-[(1H-benzimidazol-2-yl)meth-yl]-1H-imidazole-κN:N'}] N,N-dimethyl-formamide monosolvate].

Project description:In the title complex, {[CdI(2)(C(11)H(10)N(4))]·C(3)H(7)NO}(n), the Cd(II) ion is four-coordinated by two N atoms from two 1-[(1H-benzimidazol-1-yl)meth-yl]-1H-imidazole (bmi) ligands and by two terminal I(-) anions in a distorted tetra-hedral geometry. One of the two I(-) anions is disordered over two sets of sites, with refined occupancies of 0.66 (5) and 0.34 (5). The Cd(II) ions are bridged by bmi ligands, leading to the formation of a chain along [001]. Dimethyl-formamide solvent mol-ecules are located between these chains. Classical N-H⋯O hydrogen bonding between the bmi ligands and the solvent mol-ecules leads to a consolidation of the structure.

Oxido{N-[(2-oxido-1-naphthyl-κO)methyl-idene]asparaginato-κO,N}(1,10-phenanthroline-κN,N')vanadium(IV) N,N-dimethyl-formamide monosolvate.

Project description:The tridentate Schiff base ligand of the title complex, [V(C(15)H(12)N(2)O(4))O(C(12)H(8)N(2))]·C(3)H(7)NO, was derived from the condensation of 2-hy-droxy-1-naphthaldehyde and l-asparagine. The central V(IV) atom is six-coordinated by one oxide O atom, two N atoms from 1,10-phenanthroline and one N atom and two O atoms from the Schiff base ligand in a distorted octa-hedral geometry. In the crystal structure, inter-molecular N-H⋯O hydrogen bonds connect mol-ecules into centrosymmetric dimers. The C atoms of the dimethyl-formamide solvent mol-ecule are disordered over two sites with site-occupancy factors of 0.732 (13) and 0.268 (13).
