Table 1. Hyperfine Coupling Constants AHF Calculated within the DFT Frame for Simple 2Fe1Al and 1Fe2Al Model Clusters.
type of trimer | 2Fe1Al | 2Fe1Al | 1Fe2Al | 1Fe2Al |
---|---|---|---|---|
Al environment | Al–H2O | Al–OH | Al–H2O, Al–H2O | Al–H2O, Al–OH |
AHF [MHz] | 2.0 | 0.9 | 1.6, 1.7 | 1.8 (1.7), 0.9 (1.2)a |
Values in parentheses list the hyperfine coupling constants calculated for an extended 1Fe2Al cluster, in which the terminating methyl groups of the simple model cluster are replaced by phenyl groups, better resembling the BTC linkers of MIL-100.
