tert-Butyl imidazole-1-carboxylate
In the title compound, C(8)H(12)N(2)O(2), mol-ecules are inter-connected by weak C-H⋯O contacts with H⋯O distances of 2.30 Å, resulting in the formation of chains along [100]. According to graph-set analysis, the unitary descriptor of these chains is C(5). In addition, there are π-π stacking inter-actions between pyrazole rings (centroid distance = 3.878 Å and ring plane distance = 3.26 Å).

In the title compound, C(9)H(14)BNO(4), the carbonyl and boronic acid groups are essentially coplanar with the pyrrole ring and the boronic acid group has an exo-endo conformation. The exo-oriented OH is engaged in an intra-molecular O-H⋯O inter-action, while the endo-oriented one is involved in inter-molecular hydrogen bonding to form centrosymmetric dimers. A supra-molecular assembly is achie...

In the title mol-ecule, C(8)H(12)N(2)O(2)S, the imidazole ring forms a dihedral angle of 5.9 (2)° with the mean plane of the carboxyl-ate group. In the crystal, mol-ecules are linked by pairs of N-H⋯S hydrogen bonds, forming inversion dimers.
متن کاملtert-Butyl 4-formyl-1H-imidazole-1-carboxylate
In the crystal structure of the title compound, C(9)H(12)N(2)O(3), weak inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into chains. Further weak C-H⋯O hydrogen bonds together with π-π inter-actions [centroid-centroid distance = 3.672 (4) Å] between neighbouring chains lead to a double-chain structure propagating in [100].
