Can I read ~2~[Cr~2~(CO)~10~]: a Chromium(–1) Carbonyl Structure with a Very Weakly Coordinating Cation on EtoBox?

~2~[Cr~2~(CO)~10~]: a Chromium(–1) Carbonyl Structure with a Very Weakly Coordinating Cation by H. Borrmann; A. M. Pirani; G. J. Schrobilgen is a Chemistry article available to read on EtoBox.

What is ~2~[Cr~2~(CO)~10~]: a Chromium(–1) Carbonyl Structure with a Very Weakly Coordinating Cation about?

A statistical comparison of the intensities of 18 hkl/-hkl pairs prior to data collection revealed the absence of a mirror plane perpendicular to a, confirming the crystal system as monoclinic. Phenyl C--C distances were in the range 1.375 (5)-1.403 (5), with a mean of 1.389 (5).A,. All H atoms were located on difference electron-density maps and their positions refined with fixed isotropic B values equal to 1.2 times those of the attached atoms at the time of their inclusion. Bond distances were C--H 0.89 (3)-1.02 (4), N--H(7) 0.96 (4) and N--H(8) 0.85 (4),~,.
