“…592 (4) 402 (6) idealized picture of imidazole, A, and to what is H35 624(4) 267 (7) HO 1009 (4) 133 (6) found in imidazole (McMullen et al, 1979;Martinez-Carrera, 1966 We have no reasonable explanation for these observations. Structure B might be stabilized by hydrogen bonding in tings 1 and 2, but the effect is also observed in ring 3 where no hydrogen bonding is present.…”

“…Within the limits of precision, the dimensions of the coordinated imidazole rings in the present complex are the same as in free imidazole as determined by neutron diffraction (Craven, McMullan, Bell & Freeman, 1977;McMullan, Epstein, Ruble & Craven, 1979). Manganese-imidazole complexes in which the Mn n atoms have coordination numbers 6, 5 and 4, respectively, are listed in Table 3.…”

“…The smaller X-ray values for U U may be due to the crystal temperature being somewhat lower than the measured value. These X-ray intensity data were collected before we adopted the practice of measuring the changes in crystal lattice parameters over a range of temperature so as to match the temperatures of the X-ray and neutron data collection (McMullan, Epstein, Ruble & Craven, 1979). However, this may not be a satisfactory explanation.…”
