Abstract

Tri(2-furyl)phosphine (PFu ₃) reacts with [Ru ₄(μ-H) ₄(CO) ₁₂] (1) in refluxing THF to give, apart from an isomeric pair of the substituton products [Ru ₄(μ-H) ₄(CO) ₁₀(PFu ₃) ₂] (2a and 2b), the μ-phosphido cluster [Ru ₄(μ-H) ₂(CO) ₈(PFu ₃) ₂(μ-PFu ₂)(μ-n ¹,n ²-C ₄H ₃O)] (3) and a series of μ ₃- and μ ₄-phosphinidene clusters [Ru ₄(μ-H) ₂(CO) _12-x(PFu ₃) _x(μ ₃-PFu)] (x = 0 (4), 2 (5), 3 (6)) and [Ru ₄(μ-H) ₂(CO) ₉(PFu ₃) ₂(μ ₄-PFu)(μ ₃-n ¹,n ¹,n ²-C ₄H ₂O)] (7). In this one-pot reaction, the excellent facility for PFu ₃ to act as rich sources of furyl, furyne, phosphide (μ-PR ₂), and phosphinidene (μ ₃-PR and μ ₄-PR) fragments on tetrametallic frameworks has been demon-strated. The single-crystal X-ray structures of all new molecules have been determined. The structure of 7 represents the first structurally characterized example of stable furyne-containing cluster complexes of ruthenium. The electrochemical behavior and molecular orbital calculations of these metallophosphorus clusters have been examined as a function of the coordination modes of the phosphorus-containing moieties.
