MIn(HAsO4)2 (M = K, Rb, Cs): three new hydrogen­arsenates adopting two different structure types

Potassium indium bis-[hydrogen arsenate(V)], KIn(HAsO4)2, rubidium indium bis-[hydrogen arsenate(V)], RbIn(HAsO4)2, and caesium indium bis-[hydrogen arsenate(V)], CsIn(HAsO4)2, were grown under mild hydro-thermal conditions (T = 493 K, 7-8 d). KIn(HAsO4)2 adopts the KSc(HAsO4)2 structure type (space group C2/c), while RbIn(HAsO4)2 and CsIn(HAsO4)2 crystallize in the space group R-3c and are the...

Temporary negative-ion states of Na, K, Rb, and Cs.

Electronic structure and properties of isoelectronic magic clusters: Al13X (X=H,Au,Li,Na,K,Rb,Cs).

The equilibrium structure, stability, and electronic properties of the Al(13)X (X=H,Au,Li,Na,K,Rb,Cs) clusters have been studied using a combination of photoelectron spectroscopy experiment and density functional theory. All these clusters constitute 40 electron systems with 39 electrons contributed by the 13 Al atoms and 1 electron contributed by each of the X (X=H,Au,Li,Na,K,Rb,Cs) atom. A sy...

APSe6 (A = K, Rb, and Cs): Polymeric selenophosphates with reversible phase-change properties.

The ternary alkali selenophosphates KPSe6 and RbPSe6 crystallize in the polar orthorhombic space group Pca2(1) with a = 11.7764(17) A, b = 6.8580(10) A, c = 11.4596(16) A, and Z = 4 for RbPSe6. CsPSe6 crystallizes in the monoclinic space group P2/n with a = 6.877(3) A, b = 12.713(4) A, c = 11.242(4) A, beta = 92.735(7) degrees, and Z = 4. All compounds feature the one-dimensional infinite chain...

Magnetism of Alkalitetrafluoromanganates (III) AM11F4 (A = K, Rb, Cs): Neutron Diffraction, Mössbauer and Magnetization Investigations

The magnetic properties of the d 4 Jahn-Teller systems A 'Mn m F 4 with layered structures were investigated. Neutron diffraction on powders of K M n F 4 and RbMnF 4 revealed different antiferromagnetic spin arrangements below TN = 4.5 K and 2.3 K, respectively: for K M n F 4 canted antiparallel along a and b, for RbMnF 4 parallel along a and antiparallel along b, in both cases parallel along c...
