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

ABSTRACT: 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.

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

Project description:The title complex, [NiCl(2)(C(15)H(24)N(6))(C(3)H(7)NO)], is isomorphous with the Co(II) analogue. Three N-atom donors from the facially coordinating triaza macrocyclic ligand, one O-atom donor from dimethyl-formamide and two Cl(-) anions surround the Ni(II) ion in a distorted octa-hedral coordination geometry. Inter-molecular C-H⋯Cl and C-H⋯N hydrogen-bonding inter-actions link the complex mol-ecules into a three-dimensional supra-molecular architecture.

Tris(propionitrile-κN)[1,4,7-tris-(cyano-meth-yl)-1,4,7-triaza-cyclo-nonane-κN,N,N]copper(II) bis-(perchlorate) dihydrate.

Project description:In the title compound, [Cu(C(3)H(5)N)(3)(C(12)H(18)N(6))](ClO(4))(2)·2H(2)O, the Cu(II) atom lies on a threefold rotation axis and is coordinated in a distorted N(6) octa-hedral environment by three tertiary amines from the tridentate chelating aza-macrocyclic ligand and three propionitrile mol-ecules. Inter-molecular non-classical C-H⋯N hydrogen bonding inter-links the [Cu(C(3)H(5)N)(3)(C(12)H(18)N(6))](2+) cations into a two-dimensional supra-molecular sheet extending along the ab plane. The crystal packing also exhibits weak C-H⋯O inter-actions.

Triaqua-(1,4,7-triaza-cyclo-nonane-?N,N,N)nickel(II) bromide nitrate.

Project description:In the title half-sandwich compound, [Ni(C(6)H(15)N(3))(H(2)O)(3)]Br(NO(3)), the central Ni(II) ion, lying on a threefold rotation axis, is six-coordinated by three amine N atoms from the face-capping triaza macrocycle and three water O atoms in a slightly distorted octa-hedral geometry. In the crystal, O-H?O hydrogen bonding and weak O-H?Br inter-actions associate the Ni(II) cations and the counter-ions into a three-dimensional supra-molecular network.

(2,2'-Bipyridine-κN,N')bromido(1,4,7-trithia-cyclo-nonane-κS,S',S'')ruthenium(II) hexa-fluoridophosphate.

Project description:The title compound, [RuBr(C(10)H(8)N(2))(C(6)H(12)S(3))]PF(6) or [RuBr(bpy)([9]aneS(3))]PF(6) ([9]aneS(3) is 1,4,7-trithia-cyclo-nonane and bpy is 2,2'-bipyridine), exhibits a very similar octahedral coordination geometry for the Ru(2+) atom to that of its [RuCl(bpy)([9]aneS(3))](+) analogue, with only the chloride ligand being substituted by a bromide ligand. The presence of a PF(6) (-) anion (alongside with the coordinated bromide ligand) promotes the existence of an extensive network of weak C-H⋯X (X = F, Br) inter-actions.

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

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.

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

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.

Discrete water clusters in tetra-μ-cyanido-tetra-cyanidobis(1,4,7-triisopropyl-1,4,7-triaza-cyclo-nona-ne)dicopper(II)dinickel(II) tetra-hydrate.

Project description:The title tetra-cyanido-nickelate-copper complex, [Cu₂Ni₂(CN)₈(C₁₅H₃₃N₃)₂]·4H₂O, was synthesized by self-assembly using potassium tetracyanidonickelate(II) and dichlorido(1,4,7-triisopropyl-1,4,7-triazacyclononane)copper(II). The asymmetric unit contains half of a complex mol-ecule and two water mol-ecules. The entire complex has -1 symmetry and contains Ni(II) in a slightly distorted square-planar and Cu(II) in a square-pyramidal coordination environment. The crystal packing shows a discrete tetra-mer water cluster. Within the cluster, the four water mol-ecules are fully coplanar and each water monomer acts both as single O-H⋯O and O-H⋯N hydrogen-bond donor and acceptor.

(2,2'-Bipyridine-?N,N')chlorido(1,4,7-trithia-cyclo-nonane-?S,S',S'')ruthenium(II) nitrate monohydrate.

Project description:In the title compound, [RuCl(C(10)H(8)N(2))(C(6)H(12)S(3))]NO(3)·H(2)O or [RuCl(bpy)([9]aneS(3))]NO(3)·H(2)O, ([9]aneS(3) is 1,4,7-tri-thia-cyclo-nonane and bpy is 2,2'-bipyridine), the Ru(II) cation has a slightly distorted octa-hedral environment composed of three facially coordinated S atoms from ([9]aneS(3)), two N atoms from bpy and a chloride anion. The nitrate counter-ion and the water mol-ecule of crystallization are engaged in O-H?O hydrogen-bonding inter-actions, leading to a supra-molecular chain running parallel to the c axis.

Tris(nitrato-κO,O')bis-(1,10-phenanthroline-κN,N')holmium(III).

Project description:In the title compound, [Ho(NO(3))(3)(C(12)H(8)N(2))(2)], the ten-coordinate Ho(III) ion is chelated by four N atoms from two phenanthroline (phen) ligands and six O atoms from three bidentate nitrate groups. The environment around the Ho atom can be described as a distorted bicapped square anti-prism. Two phenanthroline ligands form a dihedral angle of 43.72 (13)°. Short inter-molecular distances between the centroids of the six-membered rings [3.6887 (14)-3.8374 (16) Å] indicate the existence of π-π inter-actions, which link the mol-ecules into stacks extended in the [10] direction. The crystal packing is further stabilized by weak inter-molecular C-H⋯O hydrogen bonds.
