Hydrogen Bonding and Ordering in the Solid State

This demonstrates that in essence, the H-bonding ability of diglycine substituent is not significantly perturbed by the presence of the Fc group. In fact, file 

It is noteworthy that the Cp/amide twist angle is large most likely due to the involvement of the carbonyl group in H bonding. The H bonding in 31 is similar to that of 28 in that it involves the interaction of two Fc-amides [Fc-C=0- -H-N-C (O)-Fc ti(01 NIB) = 2.977A] and two peptide amides [C=Opi,e H-Nphg
