J. Szklarzewicz et al., Products derived from the reaction of [M(CN)(4)O(H2O)](2-) with pentane-2,4-dione. X-ray crystal structure of (Ph4P)(2)[M(CN)(3)O(acac)], M = Mo or W, TRANSIT MET, 26(1-2), 2001, pp. 1-6
The reaction of pentane-2,4-dione (Hacac) with [M(CN)(4)O(H2O)](2-) ion (M
= Mo, W) gave complexes which were isolated as their tetraphenylphosphonium
salts (Ph4P)(2)[M(CN)(3)O(acac)], and were characterised by X-ray crystal
structure determination, by u.v.-vis. and H-1-n.m.r. spectroscopy, cyclic v
oltammetry, and thermogravimetric and differential thermal analysis. The st
ructure determination showed the complexes to have an approximately octahed
ral geometry, with the three cyanides in the mer configuration. Results are
compared with those of other [M(CN)(3)O(LL)](n-) ions containing bidentate
ligands LL.
