Mo 6 S 3 Br 6 : An Anisotropic 2D Superatomic Semiconductor

New class of ruthenium sulfide clusters: Ru(4)S(6)(PPh(3))(4), Ru(5)S(6)(PPh(3))(5), and Ru(6)S(8)(PPh(3))(6).

Reaction of RuCl(2)(PPh(3))(3) with S(2)(-) sources yields a family of phosphine-containing Ru-S clusters which have been characterized crystallographically and by MALDI-MS. Ru(4)S(6)(PPh(3))(4) (Ru-Ru(av) = 2.94 A) has idealized T(d)() symmetry whereas Ru(6)S(8)(PPh(3))(6) (Ru-Ru(av) = 2.82 A) adopts the idealized O(h)() symmetry characteristic of Chevrel clusters. Ru(5)S(6)(PPh(3))(5) is form...

Hexaaqua­dibromidoeuropium(III) bromide, [EuBr2(H2O)6]Br

The title compound crystallizes with the GdCl(3)·6H(2)O structure type, exhibiting discrete [EuBr(2)(H(2)O)(6)](+) cations as the main building blocks, linked with isolated bromide anions via H⋯Br hydrogen bonds to form a complex framework. The Eu atom and one Br atom each lie on a twofold rotation axis.

Valence calculations of lanthanide anion binding energies : 6 p and 6 s attachments to 4 f m ( 5 d + 6 s + 6 p ) 3 thresholds

Relativistic configuration-interaction calculations have been performed for anion states representing 6p attachments to 4f5d6s states in Gd and Tb as well as 6s attachments to 4f5d6s thresholds in Pr and Gd. The 4f subshell was treated as core-like with the same occupancy in all correlation configurations, and recently developed methods for reducing the complexity of the 4f subgroup were also e...
