Di-μ-perchlorato-bis{μ-2-[(2-pyridyl)methylaminomethyl]phenolato)dicopper(II) acetonitrile disolvate

Abstract

In the crystal of the dinuclear title compound, [Cu2(C13H13N2O)2(ClO4)2]·2CH3CN, the two bridging perchlorate ions chelate to the two CuII atoms in a μ-O:O′ fashion on opposite sides of the equatorial plane. The CuII ions display a distorted octa­hedral coordination geometry (in the usual 4 + 2 Jahn–Teller arrangement), each being coordinated by two O atoms from the two perchlorate ligands, and two N and O atoms from the reduced Schiff base ligand. The asymmetric unit contains two acetonitrile solvent mol­ecules. In the crystal structure, in addition to N—H⋯O hydrogen bonds, there are weak C—H⋯O inter­actions between the perchlorate O atoms and the reduced Schiff base ligand. C—H⋯N inter­actions are also present.

“…Data collection: CrysAlis CCD (Oxford Diffraction, 2008); cell refinement: CrysAlis RED (Oxford Diffraction, 2008); data reduction: CrysAlis RED; program(s) used to solve structure: SHELXS97 (Sheldrick, 2008); program(s) used to refine structure: SHELXL97 (Sheldrick, 2008); molecular graphics: SHELXTL (Sheldrick, 2008); software used to prepare material for publication: SHELXTL. The present complex was synthesized by displacement of weakly coordinated perchlorate anions from a structurally determined complex (Assey et al, 2009) The crystal structure of the resulting complex, bis{µ-O-[2-((pyridin-2-ylmethylamino)methyl)phenolato]thiocyanatocopper(II)} has been determined. In this instance, two thiocyanate ligands were ligated to the copper(II) complex as a result of displacement of weakly coordinated perchlorate ligands.…”

Magnetostructural Properties of Some Doubly-Bridged Phenoxido Copper(II) Complexes

“…Different strategies have been employed in the design of this class of compounds. The first approach was achieved though the interaction Cu(II) salts with tridentate ligand-based phenolates in their skeletons [ 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 ], and the second approach was via the design of bicompartmental phenolates bearing two pendent arms of N-donor groups [ 1 , 2 , 3 , 4 , 5 , 6 , 42 , 43 ]. A third approach was also used through the design of tripodal pyridyl tetradentate ligands containing one or two phenolate arms [ 12 , 14 , 15 , 20 , 29 , 44 , 45 , 46 , 47 , 48 , 49 , 50 , 51 ].…”
