“…In metallide-oxides of the anti-perovskite-type structure like Ba 3 SnO, the O p-states are also found in this region [7]. For all compounds, the charges for the hydride ions of À0.74 and the volumes of the Bader basin (V BB = 13-14 Á10 6 pm 3 ) also nicely compare to the data calculated for the salt BaH 2 [H(1): q = À0.655, V BB = 12.0 Á10 6 pm 3 ; H(2): q = À0.672, V BB = 14.9 Á10 6 pm 3 ] and for intermetallic hydrides like Ba 9 ½In 4 ½H (q = À0.740, V BB = 14.8 Á10 6 pm 3 [40]). The hydrogen partial DOS (pDOS) is found in the same energy range as the oxygen p bands.…”

“…(In contrast, other H À containing metallides like Ba 9 In 4 H [40] or Ca 54 In 13 B 4Àx H 23þx [56] exhibit no alkaline-earth rich structure regions and are thus better compared to the family of simple metallide oxides, like e.g. Ba 3 SnO).…”

“…Bei quantitativem Einbau von Hydrid‐Anionen würde man selbst bei statischen Messungen ein scharfes Signal hoher Signifikanz bei einer Verschiebung im Bereich von ca. −6 bis −8 ppm erwarten . Das erhaltene breite und schwache Signal um 0 ppm stammt viel wahrscheinlicher von geringfügiger Verunreinigung mit Hydrolyseprodukten der empfindlichen Substanzen oder von Feuchtigkeitsspuren in der Wandung des NMR‐Rotors.…”

“…Cs 9 Pt 4 H zeigt salzartigen Charakter mit Platin in der Oxidationsstufe −II wie in Cs 2 Pt und mit Hydridionen wie in CsH. Es ist sinnvoll, Cs 9 Pt 4 H mit Ba 9 In 4 H zu vergleichen, das ähnlich wie Cs 9 Pt 4 H kristallisiert, zu diesem aber nicht isotyp ist. Trotz der analogen Formel zeichnet sich Ba 9 In 4 H durch einen Überschuss an Elektronen aus, der für seinen metallischen Charakter verantwortlich ist.…”
