چکیده
The title tetra-nuclear complex, [Cu(4)Cl(6)O(C(13)H(11)N(3))(4)], features a tetra-hedral arrangement of copper(II) ions bonded to the central O atom (site symmetry [Formula: see text]). Each of the six edges of the Cu(4) tetra-hedron is bridged by a chloride ion (one of which has site symmetry 2), so that each copper ion is linked to the other three metal ions through the central O atom and through three separate chloride-ion bridges. The fifth coord-ination position, located on the central Cu-O axis on the outside of the cluster, is occupied by an N atom of the mono-dentate 1-(pyridin-2-ylmeth-yl)-1H-benzimidazole ligand. The resulting coordination geometry of the metal ion is a distorted trigonal bipyramid with the O and N atoms in the axial positions. The dihedral angle between the benzimidazole ring system and the pendant pyridine ring is 61.0 (2)°.

In the title solvate, [Cu4(μ2-Cl)6(μ4-O)(C4H9NO)4]·2CH3OH, each Cu(2+) ion in the tetra-nuclear complex has a trigonal-bipyramidal coordination arising from three bridging chloride ions in equatorial positions and the central μ4-O(2-) ion and morpholine N atom in axial positions. The morpholine rings adopt chair conformations, with the N-Cu bonds in equatorial orientations. In the crystal, the ...
