ChemInform Abstract: STRUCTURE OF BIS(PHTHALOCYANINATO)NEODYMIUM(III)

Abstract

Eine Röntgenuntersuchung des Titelkomplexes, der ein saures H‐Atom enthält und als CH, C12 ‐Monosolvat vorliegt, zeigt, daß er Sandwichstruktur hat und in der Raumgruppe P212, 2, kristallisiert.

Selective Crystallization of Four Bis(phthalocyaninato)neodymium(III) Polymorphs

“…54 The last polymorph is a CH2Cl2 solvate phase which has also been previously identified, though the space group was mis-assigned as P212121 instead of Pnma. 14 reduces HNdPc2 + to NdPc2 -(solid purple line). e) Subsequent addition of more acetic acid (approx.…”

“…Additionally, there has been confusion in the previously published literature about the exact chemical composition of the NdPc2 species. 14,15 Bis(phthalocyaninato)lanthanoid complexes can easily undergo oxidation and reduction reactions to give the charged complexes LnPc2 + and LnPc2 -, respectively. The neutral and negatively charged species are deep green or purplish blue, while the cation is red, making them perfect candidates for identification by UV-Vis spectroscopy.…”

“…5 Because of these properties, diphthalocyanine complexes have been integrated in solar cells 6 and field effect transistors 7 , and studied as molecular magnets 8 and information storage materials. 9 Modifications of Kirin and Moskalev's original synthesis resulted in double-decker compounds across the lanthanoid series [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25] (with the exception of radioactive promethium), as well as for several actinoid [26][27][28][29][30][31] , p-block [32][33][34][35] , and transition metals. 36 Crystals of varying quality used in structure determinations were grown through electrochemical methods, solvent-solvent diffusion, and sublimation.…”

“…Additionally, there has been confusion in the previously published literature about the exact chemical composition of the some of the compounds, in particular for the NdPc2 species. 14,15 Bis(phthalocyaninato)lanthanoid complexes can easily undergo oxidation and reduction reactions to give the charged complexes LnPc2 + and LnPc2 -, respectively.
