BaNi2In4Sc4O15 with BaV10O15-Structure, but Ordered Metal DistributionSingle crystal X-ray investigations of BaNi2In4Sc4O15 [space group D2h18-Cmca, a = 12.146; b = 10.880; c = 9.834 Å; Z = 4] show a statistical distribution of Ni2+ and Sc3+ of one of the possible point positions. The other oxygen octahedra are occupied by In3+ and Sc3+. This is the difference to compounds of the formula BaM10O15 (M = V, Cr, Ni/Cr) with total statistical metal distribution.
Notes:
Einkristalluntersuchungen an BaNi2In4Sc4O15 [Raumgruppe D2h18-Cmca. a = 12,146; b = 10,880; c = 9,834 Å; Z = 4] zeigen, daß Ni2+ nur mit Sc3+ eine der oktaedrisch koordinierten Metallpunktlagen statistisch besetzt. Alle anderen Polyeder sind frei von Ni2+, womit diese Verbindung sich von den Oxiden BaM10O15 (M = V, Cr, Ni/Cr) mit total statistischer Metallverteilung unterscheidet.
