get_cif

Active

declared in 0.1.0

Fetch the full CIF (Crystallographic Information File) for a COD structure by its numeric COD ID — the actual machine-readable structure: symmetry operations and the atom sites (element, fractional x/y/z coordinates, occupancy). Use after search_structures/get_structure when you need the real atomic structure, not just the metadata/link. Returns the CIF text plus a parsed summary (formula, space group, cell, atom count). Keyless.
