Af. Stange et al., A TETRAGONAL BISPHENOIDAL TETRACOPPER(I) ARRANGEMENT SUPPORTED BY A POTENTIALLY TRIDENTATE LIGAND CONTAINING THIOLATE, SECONDARY AMINE, AND2-PYRIDINE FUNCTIONS - HYDROGEN-BONDED INSTEAD OF CU(I)-COORDINATED PYRIDINE RINGS IN AN S-4-SYMMETRICAL COMPOUND, Inorganic chemistry, 35(13), 1996, pp. 4087
The S-4-symmetric copper(I) tetramer C(u)4(MEPA)(4), MEPAH = N-(2-merc
aptoethyl)picolylamine, exhibits a tetragonal bisphenoidal (D-2d) arra
ngement of the metal centers. The MEPA(-) ligands use mu-thiolate and
the amine nitrogen centers for coordination, while the 2-pyridyl group
s are not involved in Cu(I) coordination but in an intramolecular hydr
ogen-bonding network with the metal-bound and thus cooperatively activ
ated secondary amine functions.
