Abstract
Orange crystals of CpMn(CO)(2)(RC equivalent to CR), where R = Ph or CH2OH
(I and II, respectively), were prepared by the photochemical reaction of Cp
Mn(CO)(3) with tolan and 1,4-butynediol. According to the X-ray structural
analysis of I and II, the coordinated triple bond occupies the position of
the displaced CO group in a CpMn(CO)(3) "piano stool" and elongates from 1.
19 Angstrom in R2C2 to 1.242(5) or 1.233(4) Angstrom, respectively, while t
he R-C equivalent to C angles decrease, on the average, from 180 degrees to
154.5(4)degrees or 152.8(3)degrees, respectively.
