Task: Please create a description for a molecule based on its representation.
SMILES: C[C@@]1(CC(=O)[O-])c2cc3[n-]c(cc4nc(cc5[n-]c(cc(n2)[C@H]1CCC(=O)[O-])[C@@](C)(CC(=O)[O-])[C@@H]5CCC(=O)[O-])C(CC(=O)[O-])=C4CCC(=O)[O-])c(CCC(=O)[O-])c3CC(=O)[O-].[Ni]
Constraint: Answer the question with complete sentences.
Result: The molecule is a cyclic tetrapyrrole anion obtained by deprotonation of the carboxy groups of nickel-sirohydrochlorin; major species at pH 7.3. It is a conjugate base of a nickel-sirohydrochlorin.
