  Abstract:  The paper aims to denominate and present the largest synthesized and structurally characterized molecules. To begin with, the terms chemical compound and molecule are analyzed and differentiated. Two types of very large/giant molecules are defined: a) collective large molecules, generated through an inflationary multiplication (in one, two or three dimensions) of one or several species of smaller discrete molecules and b) discrete/individual large molecules, constructed by actual synthesis through the assembly of appropriate building blocks. The candidates for the title of the largest molecule are sought among the discrete giant molecules. Reviewed are very large molecules synthesized over the past 30 years, starting with the classical molecular polyoxometalate clusters [As4W40] and [P8W48] and continuing with the new supramolecular polyoxometalate clusters, such as [Mo57M6], [Mo132], [Mo72Fe30], [Mo102], [Mo154], [Mo176], [Mo248] and [Ln16As12W148]. The [Mo368] cluster, currently the largest synthesized and structurally characterized molecule, concludes the presentation. The possibility of synthesizing even larger molecules is also envisaged.
