Résumé en anglais
In a model study the crystal structures of shandite (Pb2Ni3S2), parkerite (Bi2Ni3S2) and their Pd homologues are investigated in terms of ordered half antiperovskites AM3/2S (A = Pb, Bi; M = Ni, Pd). This addresses fundamental ...Lire la suite >
In a model study the crystal structures of shandite (Pb2Ni3S2), parkerite (Bi2Ni3S2) and their Pd homologues are investigated in terms of ordered half antiperovskites AM3/2S (A = Pb, Bi; M = Ni, Pd). This addresses fundamental questions on the structural relations, ordering and chemical bonding. From crystal structure investigations a new cubic parkerite variant is presented for Bi2Pd3S2 that fits in an ordering model equivalently to shandite and parkerite...< Réduire
