Close-up of the N-propargylcarboxamide group in (I) and its weak O—H⋯C, N—H⋯O and C—H⋯O interactions. Numbers with two decimal places are H⋯acceptor distances, numbers with three decimal places are corresponding C/N/O—acceptor distances (Å). Symmetry codes ii, iii, and iv are given in Table 1, code v is −x + ![]() ![]() |
