Abstract
Thermal treatment of Ce-2(OPri)(8)((PrOH)-O-i)(2) yielded Ce-4(mu(4)-O )(OPri)(14) by desolvation under mild conditions. The tetranuclear oxo alkoxide has been characterized by elemental analysis, FT-IR, H-1 NMR and X-ray diffraction. The structure is described as e-4(mu(4)-O)(mu(3 )-OPri)(2)(mu-OPri)(4)(OPri)(8)]. The Ce-4(mu(4)-O) core corresponds t o a distorted flattened tetrahedron, with two hexa- and two hepta-coor dinated metals. The Ce-O bond lengths spread over the range 2.03(2) to 2.54(1) Angstrom, and follow the order Ce-OR < Ce-mu OR < Ce mu(3)-OR . Copyright (C) 1997 Elsevier Science Ltd.
