„Supramolekulare“ Festkörperchemie: einander durchdringende diamantartige Gerüststrukturen mit U4+-Ionen und zweizähnigen molekularen P2S62−-S,S′-„Stäben“ in UP4S12

Abstract: Organische Verbindungen können sich bei tiefen Temperaturen zu organisierten Aggregaten anordnen, die zu molekularer Erkennung fähig sind und als biomimetische Systeme dienen können. [1] Dies führte in der supramolekularen organische Chemie zu erstaunlichen Ergebnissen, [2] unter anderem zur Bildung dreidimensionaler (3D-) Netzstrukturen vom Super-Diamant- [3] und Super-Wurtzit-Typ, [4] die durch Wasserstoffbrückenbindungen stabilisiert werden. Im Bereich der anorganischen Koordinationschemie schlugen Hoskins… Show more

“…However, high and variable coordination numbers of the early transition metals, [19, 30, 31] lanthanides, [26, 42] or actinides [16, 30, 43] combined with the condensation equilibria of chalcophosphates44 may lead to structural arrangements of astounding complexity, as the above examples indicate. Bidentate ligands such as PS 4 3– or P 2 S 6 2– can act as quasilinear twofold bridging connectors between 6‐ or eight‐coordinate transition metal atoms, thus leading to a pseudotrigonal (for 6‐coordination as in A Ti 2 (PS 4 ) 3 ( A = Li, Na, Ag) [25c, 40] and Ag 2 NbTi 2 P 6 S 25 ,40 or pseudotetrahedral (for 8‐coordination as in U(P 2 S 6 ) 2 ,16 CsLiU(PS 4 ) 2 , or Na 2 U(PS 4 ) 2 ) environments for the metal atoms. The coordination preferences of the metal component are an important factor in the choice of the structure (and properties) of thiophosphates.…”

“…The coordination preferences of the metal component are an important factor in the choice of the structure (and properties) of thiophosphates. The structures of the title compound or of U(P 2 S 6 ) 2 16 indicate that the coordination mode of the metal atom combined with the connectivity mode and size of the “linear” (rod‐like) PS 4 3– or P 2 S 6 2– ligands may lead to the formation of complex network structures…”

“…UP 4 S 12 contains three independent polymeric diamond-like U(P 2 S 6 ) 2 frameworks in which the P 2 S 6 units act as molecular rods linking the pseudo-tetrahedral U 4ϩ centres. 124 The novel [P 2 S 10 ] 4Ϫ anion has been formed in Cs 4 P 2 S 10 and consists of two PS 4 tetrahedra connected via a disulfide, thus producing a [S 4 ] 2Ϫ fragment in the anion. 125 Cs 8 U 5 -(P 3 S 10 ) 2 (PS 4 ) 6 contains the new [P 3 S 10 ] 5Ϫ building block and has been shown to contain tetravalent U as part of an extended electronic system.…”
