Task: Please create a text description for a molecule based on its representation.
SMILES: C1=Cc2nc1cc1ccc(cc3ccc(cc4ccc(cc5nc2C=C5)[nH]4)[nH]3)[nH]1
Constraint: Answer the question with full sentences.
Result: The molecule is a cyclic pentapyrrole where the five pyrrole units are joined at their 2- and 5-positions via four methine linkages and one direct 2-5'-linkage.
