Heterobimetallic Chalcogenidometallate Strands: Synthesis, Structure, Magnetism, and Conductivity

Two salts with one-dimensional, SiS2-type telluridostannate chain anions {[MSnTe4]2−}n, Rb2[HgSnTe4] (2) and (NMe4)2[MnSnTe4] (3), were prepared by the reactions of [SnTe]4− anions with Hg2+ or Mn2+ ions in solution. We present the crystal structures of 2 and 3, as well as the magnetic properties of the previously reported Cs+ analogue Cs2[MnSnTe4] (1)

Unique Manganese Phosphorus Complex with a Mn5P7 Core: Synthesis, Molecular Structure, and Magnetic Properties

The manganese phosphorus cluster [Mn5{N(SiMe3)2}{μ4-PSiiPr3}2{μ-P(H)SiiPr3}5] (1) containing an unusual Mn5P7 core structure and three short Mn-Mn distances was obtained from the reaction of Mn{N(SiMe3)2}2 with H2PSiiPr3. Quantum chemical investigations indicated the presence of comparably strong intramolecular antiferromagnetic interactions leading to a total S ) 5/2 spin ground state, which was confirmed by magnetic measurements

Inorganic Frameworks from Selenidotetrelate Anions [T2Se6]4- (T ) Ge,Sn): Synthesis, Structures, and Ionic Conductivity of [K2(H2O)3][MnGe4Se10] and (NMe4)2[MSn4Se10] (M ) Mn, Fe)

Syntheses, structures, and physical properties of three inorganic framework compounds [K2(H2O)3][MnGe4Se10] (1), (NMe4)2[MnSn4Se10] (2), and (NMe4)2[FeSn4Se10] (3) are presented. The title compounds are based on a prominent open framework anionic structure; in these cases, however, they contain K+, the smallest type of counterion to be included so far (1), or represent Sn analogues (2, 3). Both changes with respect to related compounds are reflected in peculiar physical properties, such as ion conductivity or relatively small band gaps
