The synthesis and X-ray structure of [PP-N] [W(CO)5CH2CN] are reported. The complex crystallizes in the triclinic space group P1, with unit cell dimensions a = 12.771 (4) , b = 13.410 (4) , c = 13.850 (5) , = 54.41 (3), = 68.65 (3), = 83.98 (3), V = 1988 (2) 3, Z = 2, and RF =4.13%. The W-C-H2CN bond distance was found to be 2.330 (8) , a value quite similar to that found in the W-CH3 analogue. Unlike W(CO)5CH3, the W(CO)5CH2CN anion does not react with carbon dioxide even under very high pressure. Furthermore, the cyanoacetate derivative, W(CO)5O2CC-H2CN, prepared from cyanoacetate and W(CO)5THF, does not undergo decarboxylation either in solution or in the solid state. On the other hand, the W(CO)5O2CCH2C-N complex is a catalyst for the homogeneous decarboxylation of cyanoacetic acid. 1991, American Chemical Society. All rights reserved.
