The title compounds, C H N O S (I) and C H N O S (II), are structural analogs of the alkaloid Thio-sporine B. Both mol-ecules adopt a near-planar V-shaped conformation, which is consolidated by intra-molecular N-H⋯N and C-H⋯O hydrogen bonds. The crystal structure of (I) consists of mlecular stacks along the axis, in which the mol-ecules are linked to each other by π(S)⋯π(C) inter-actions. In the crystal of (II), mol-ecules are linked into chains by C-H⋯O hydrogen bonds and the chains are cross-linked into (100) sheets by π-π stacking inter-actions.
