Popis:	Thermal treatment of Ce2(OPri)8(PriOH)2 yielded Ce4(μ4-O)(OPri)14 by desolvation under mild conditions. The tetranuclear oxoalkoxide has been characterized by elemental analysis, FT-IT, 1H NMR and X-ray diffraction. The structure is described as [Ce4(μ4-O)(μ3-OPri)4(μ-OPri)4(OPri)8]. The Ce4(μ4-O) core corresponds to a distorted flattened tetrahedron, with two hexa- and two hepta-coordinated metals. The CeO bond lenghts spread over the range 2.03(2) to 2.54(1) A and follow the orcer CeOR
