      Planar Elongated B12 Structure in M3B12 Clusters (M = Cu-Au) (2024) 

      Solar-Encinas, José; Vásquez-Espinal, Alejandro; Leyva-Parra, Luis; Yañez, Osvaldo; Inostroza, Diego; Valenzuela, Maria Luisa; Orellana, Walter; Tiznado, William (MDPI, 2023)
      Here, it is shown that the M3B12 (M = Cu-Au) clusters’ global minima consist of an elongated planar B12 fragment connected by an in-plane linear M3 fragment. This result is striking since this B12 planar structure is not ...

      Searching for Systems with Planar Hexacoordinate Carbons (2024) 

      Inostroza, Diego; Leyva-Parra, Luis; Yañez, Osvaldo; Solar-Encinas, José; Vásquez-Espinal, Alejandro; Valenzuela, Maria Luisa; Tiznado, William (MDPI, 2023)
      Here, we present evidence that the D2h M2C50/2+ (M = Li-K, Be-Ca, Al-In, and Zn) species comprises planar hexacoordinate carbon (phC) structures that exhibit four covalent and two electrostatic interactions. These findings ...
