Nonagermanide clusters are widely used in inorganic synthesis and are actively studied by experimentalists and theoreticians. However, chemical bonding of such versatile species is still not completely understood. In our work we deciphered a bonding pattern for various experimentally obtained nonagermanide species. We localized the electron density via the AdNDP algorithm for the model structures ([Ge9]4−, [Ge9{P(NH2)2}3]−, Cu[Ge9{P(NH2)2}3] and Cu(NHC)[Ge9{P(NH2)2}3]) and obtained a simple and chemically intuitive bonding pattern which …

The synthesis and characterization of a new phthalocyanine(Pc) Mn-nitride complex, (OEtPc)MnN (2; OEtPc= 1,4,8,11,15,18,22,25-octaethoxy-Pc), as well as its stable, readily accessible oxidized (2+ and 22+) and reduced (2-, 22-) congeners is reported. This unique isostructural series displays switchable aromatic character spanning the aromatic (2), non-aromatic (22+), and antiaromatic (22-) triad, in addition to the open-shell radical states (2+, 2-). All complexes were structurally characterized and displayed significant structural distortions at the redox extrema (22+, 22-) consistent with proposed [16 or 18]annulene π ring circuit models. Spectroscopic and computational studies further support these models. This isolated, fully characterized, isostructural series spanning …
