  Direct photolytic route to trans-Cr(CO)4(AsPh3)2 and crystal structures of cis-Mo(CO)4(AsPh3)2 and cis-W(CO)4(AsPh3)2

  摘要：

  The preparation of trans-Cr(CO)(4)(AsPh3)(2) is accomplished in reasonable yield by the direct photolysis of a solution of Cr(CO)(6) and an excess of AsPh3 in heptane. The structures of cis-Mo(CO)(4)(AsPh3)(2) and cis-W(CO)(4)(AsPh3)(2) are reported. These are found to be isostructural and consist of distorted octahedral geometries with As-M-As angles of 102.56(2) and 102.62(2)degrees for M = Mo and W, respectively. The Mo-As distances of 2.6428(9) and 2.6489(9) Angstrom are significantly longer than those in the W analogue at 2.6384(6) and 2.6361(6) Angstrom. On the basis of a comparison to literature data, the AsPh3 ligands in these molecules can be described as extremely compressed. (C) 2001 Elsevier Science B.V. All rights reserved.
