Datasets usually provide raw data for analysis. This raw data often comes in spreadsheet form, but can be any collection of data, on which analysis can be performed.
The reactions of (dpp-BIAN)Zn−Zn(dpp-BIAN) (1) with PhCCH and of [(dpp-BIAN)Zn(μ-I)]2 (2) with potassium hydride yield the binuclear complexes [(dpp-BIAN)Zn(μ-CCPh)]2 (3) and [(dpp-BIAN)Zn(μ-H)]2 (4), respectively (dpp-BIAN = 1,2-bis[(2,6-diisopropylphenyl)imino]acenaphthene). Complex 3 is also obtained by thermal dehydrogenation of [dpp-BIAN(H)]Zn(CCPh) (5), which in turn can be prepared by reacting ZnI2 with equimolar amounts of [dpp-BIAN(H)]Na and PhCCNa. The paramagnetic compounds 3 and 4 have been characterized by ESR spectroscopy; the diamagnetic complex 5, by 1H NMR spectroscopy. The molecular structures of 3 and 4 have been determined by single-crystal X-ray diffraction. The electronic structure of complex 4 has been examined by DFT.
