Figure 1. Perspective ORTEP drawing of the [Py, Co, O (OAc), OH]+ cation in crystalline [Py3C030 (OAc), 0H][PyCoBr3]. Nonhydrogen atoms are represented by thermal vibration ellipsoids drawn to encompass 50% of the electron density; hydrogen atoms are represented by arbitrarily small spheres which are in no way representative of their true thermal motion. are clusters where M= Co because these clusters may be involved in the ...
