چکیده

The crystal structure of di-μ(3)-chlorido-tetra-μ(2)-chlorido-dichloridoocta-(imidazole-κN)tetra-manganese(II) ethanol 1.234 solvate, [Mn(4)Cl(8)(C(3)H(4)N(2))(8)]·1.234C(2)H(5)O or [Mn(4)Cl(8)(Him)(8)]·1.234EtOH, where Him is imidazole (C(3)H(4)N(2)), is based upon two Mn(4)Cl(4) cubes which share one face, and which each lack one manganese vertex, giving a Mn(4)Cl(6) unit. This contains two different octa-hedral coordination environments for the Mn atoms. Mn1 is coordinated by four bridging chlorido ligands and two imidazole N atoms, whereas Mn2 is coordinated by three bridging and one terminal Cl and two imidazole N atoms. The remaining two Mn centres are generated by inversion symmetry. A partial occupancy solvent mol-ecule (ethanol) is present. The crystal structure displays several N-H⋯Cl and N-H⋯O hydrogen bonds.

The centrosymmetric mol-ecule of the title complex, [Cd(4)Cl(8)(C(3)H(4)N(2))(6)(C(3)H(7)NO)(2)], contains four Cd(II) atoms, six imidazole, two dimethyl-formamide and eight chloride ligands. The structure shows a novel chloride-bridged tetra-nuclear cadmium quasi-cubane cluster. The coordination geometry of all Cd(II) atoms is distorted octa-hedral, with the two metal atoms in the asymmetric u...

Two-dimensional Manganese(II) Coordination Polymer Complex Containing Aqua, Diethyl Phosphate and Chloride Ligands: Synthesis, Spectroscopic Characterization, Thermal Analyses, and Crystal Structure

A new two-dimensional manganese(II) coordination polymer, [Mn(μ-DEP)(μ-Cl)(H2O)2]n (1) (DEP is diethyl phosphate), was prepared from the reaction of MnCl2.4H2O and TEP (TEP is triethyl phosphate) ligand in mixture of H2O/CH3OH (1:10) at 40 °C. Suitable crystals of this complex for crystal structure determination were obtained by slow evaporation of the produced colorless solution at room temper...

Manganese(II) chloride complexes with pyridine N-oxide (PNO) derivatives and their solid-state structures

Three manganese(II) N-oxide complexes have been synthesized from the reaction of manganese(II) chloride with either pyridine N-oxide (PNO), 2-methyl-pyridine N-oxide (2MePNO) or 3-methyl-pyridine N-oxide (3MePNO). The compounds were synthesized from methano-lic solutions of MnCl2·4H2O and the respective N-oxide, and subsequently characterized structurally by single-crystal X-ray diffraction. Th...

The asymmetric unit of the crystal structure of the title compound, [Cd(2)Cl(4)(C(5)H(8)N(2))(3)](n), contains two Cd(II) cations, three 1-ethyl-1H-imidazole ligands, and four Cl(-) anions. The two Cd(II) atoms have quite different coordination environments: one is octa-hedrally coordinated by four Cl atoms and two N atoms from two 1-ethyl-1H-imidazole ligands, and the second is in a severely d...

The title compound, [Pd(4)(CH(2))(2)Cl(4)(C(28)H(40)P(2))(2)]·5C(4)H(8)O, possesses a tetra-nuclear palladium core with four bridging chlorido ligands and two bridging methyl-ene units, as well as two bridging anthracene-based bis-phosphine ligands. This tetra-nuclear complex can be considered as being composed of two μ-chlorido-bridged LPd(2) units. The structural motif of these LPd(2) units s...
