Die Struktur von [Pd₆Cl₁₂] in bei Raumtemperatur chemisch gezüchteten Einkristallen

Abstract

Eine Verringerung des CO‐Partialdrucks genügt, um aus dem Gleichgewicht (a) in Thionylchlorid (Solv.) Einkristalle von [Pd6Cl12] bei Raumtemperatur zu erhalten. Die Einkristall‐ und Pulver‐röntgenographische Charakterisierung dieses PdII‐Chlorids wird hier beschrieben.

Ionothermal Syntheses, Crystal Structures, and Chemical Bonding of the Rhodium‐Centered Clusters [RhBi9]4+and [(RhBi7)I8]

“…Overall, the arrangement of the bismuth atoms is even closer to spherical than in the case of the empty cation. The same effect has been observed for the empty Sn 9 4-and Pb 9 4- The obvious geometrical similarity suggests a rhodium(-I) atom with a closed-shell d 10 Tables S4-S12 and visualized in Figures S5-S8 (Supporting Information).…”

“…Despite the abundance of stable polycations of the maingroup elements, [1] only one type with endohedral atoms has been isolated: the filled arachno clusters of bismuth [1d] [M@Bi 10 ] n+ with n = 4 for M = Pd, Pt, and n = 5 for M = Au (Figure 1). [2] The @ symbol implies, in principle, comparatively weak interactions between a guest and the host and, moreover, a host that is stable even without the guest.…”

“…Br, I). [9] They only exist as "filled" variants, in contrast to transition metal cages M 6 X 12 like Pd 6 Cl 12 in β-PdCl 2 [10] or [Nb 6 Cl 12 ] 2+ in Nb 6 Cl 14 . [11] The scarcity of ligand-free filled polycations is rather surprising regarding the abundance of anionic main-group element clusters that are centered by electron-rich transition elements.…”

“…[14] The b-form consists of discrete molecules of [Pd 6 Cl 12 ] that have an octahedral array of metal atoms. [13,15,16] Each metal atom is again surrounded by four equivalent chlorine atoms that bridge edges of the octahedron. The b-form can be prepared in several ways.…”

“…[3] Danach kristallisiert b-PdCl 2 mit rhomboedrischer Symmetrie in der Raumgruppe R " 3 3 und mit einer Formeleinheit Pd 6 Cl 12 pro Elementarzelle. Die Pd 6 Cl 12 -Cluster bilden analog zu Pt 6 Cl 12 [4,5] isolierte Würfel, auf deren Würfelflächen PdCl 4 -Quadrate liegen.…”
