Na4Ba9MnN3: A New Subnitridometalate with Trigonal Planar Anions [MnIIIN3]6−

Zeitschrift für anorganische und allgemeine Chemie, Volume 652, Issue 4, 17 March 2026.
The new subvalent nitridomanganate(III) Na4Ba9MnN3 contains structural elements known from ionic subnitridometalates as well as from intermetallic phases. In similarity to Ba3MnN3, isolated trigonal planar nitridomanganate(III) anions (MnN3)6−, coordinated by barium atoms represent the ionic region, while mixed barium‐sodium icosahedra known from ...

On New Alkaline Sulfatometallates: Cs6[(WO2)2O(SO4)4], K8[(MoO2)2(SO4)6], K7.9Sr0.1[(WO2)2(SO4)6] and Na4[MoO2(SO4)3]

Zeitschrift für anorganische und allgemeine Chemie, Volume 652, Issue 4, 17 March 2026.
Two new alkaline sulfatometallates show promising optical absorption, emission and even non‐linear optical properties together with an astonishingly high thermal stability. The new sulfatotungstate Cs6[(WO2)2O(SO4)4] exhibits a hitherto unknown anion with an unusual W–O–W angle of 180° and edge‐sharing WO6 and SO4 polyhedra.

Tuning High Temperature Performance Through Targeted Halide Substitution in a Bis(Imino)Pyridine‐Iron Ethylene Polymerization Catalyst

Journal of Applied Polymer Science, Volume 143, Issue 11, March 15, 2026.
Through systematic developments in catalyst design, we report a series of exceptionally active on iron catalysts for the polymerization of ethylene that can run at high operating temperature forming highly linear polyethylene waxes with narrow dispersity and high levels of vinyl chain ends that could be influenced by the operating temperature.
