  P ₈ and P ₁₂ as Complex Ligands

  摘要：

  AbstractThe thermal and/or photochemical reaction of [Cp‴Co(CO)2] (1), Cp‴ = 1,2,4‐tBu3C5H2, with white phosphorus, P4, gives besides [(Cp‴Co)2 (P2)2] (2) the trinuclear complexes [(Cp‴Co)3P8] (3) and [(Cp‴Co)3P12] (4), the Pn ligands of which form P5–P3 and P5–P7 skeletons, structural motifs, which formally can be derived from Hittorf's phosphorus. The X‐ray crystal structure analysis of 3 confirmed its P5–P3 framework.

  One-Electron Oxidation of Heterodinuclear Organometallic Compounds Having Polyphosphido Bridges

  摘要：

  The electrochemical behavior of several heterometallic compounds having polyphosphido bridges has been investigated. Reversible one-electron oxidations were observed for Cp*Fe-(P-5)TaCp" (2), Cp*Fe(P-5)[Ir-2(CO)(2)CP*(2)] (3), and CP''' 2CO2(P-2)(2) (4) (Cp* = C5M5, CP" = C5H3 Bu-t(2) = (C5H2Bu3)-Bu-t). In contrast to the pseudo-sandwich polyphosphido complex Cp*FeP5 (1), compounds 2-4 undergo very facile oxidations and the corresponding monocations may be generated by bulk electrolysis or by reaction with ferrocenium ion. E-1/2 values (vs Cp2Fe0/+) for the oxidations are -0.24 V for 2, -0.58 V for 3, and -0.33 V for 4 in CH2Cl2/0-1 M [NBu4] [PF6], in contrast to 0.57 V for 1. Although ESR spectra of 2(+) display hyperfine coupling to Ta-181, the SOMO appears to have only minor Ta character. IR spectroelectrochemistry of the 3/(3+) couple reveals an increase of nu(CO) of only 11 cm(-1), indicating that the oxidation of 3 also occurs predominantly at the iron center. The fact that the Fe-based oxidations of 2 and 3 are more negative than that of 1 by ca. 0.8 and 1.15 V, respectively, is ascribed to differences in the iron formal oxidation state which arise from the structural variations of the P-5 bridging groups.

  Under control: Controlled self‐aggregation of P4 to extended neutral polyphosphorus cages was achieved in the presence of cobalt complex fragments. X‐ray structure analyses of P12, P16, and P24 ligand complexes give insights into the formation of aggregated allotropes of phosphorus from elemental P4.

  the monoanions [K(18-c-6)(dme)2 ][(Cp'''Co)2 (μ,η4 :η4 -E4 )] (E=P (7), As (8)) were isolated. Further reduction of 7 leads to the dianionic complex [K(18-c-6)(dme)2 ][K(18-c-6)][(Cp'''Co)2 (μ,η3 :η3 -P4 )] (9), in which the cyclo-P4 ligand has rearranged to a chain-like P4 ligand. Further reduction of 8 can be achieved with an excess of potassium under the formation of [K(dme)4 ][(Cp'''Co)2 (μ,η3 :η3
