Every refinement confirms two interpenetrating face-centred cubic lattices offset by (1/4, 1/4, 1/4) with exact tetrahedral 4-coordination around each carbon atom. https://w3id.org/delphi/resource/assessment/bragg1915-03--gemini http://purl.org/dc/terms/subject https://w3id.org/delphi/resource/concept/dataset-resolvability-0.2.0 https://w3id.org/delphi/resource/assessment/bragg1915-03--gemini http://www.w3.org/1999/02/22-rdf-syntax-ns#type https://w3id.org/delphi/ontology/LLMClaimAssessment https://w3id.org/delphi/resource/assessment/bragg1915-03--gemini http://www.w3.org/2000/01/rdf-schema#comment Proposed test with existing data: In refined crystal structures of cubic diamond (space group Fd-3m), verify the fractional atomic coordinates of carbon atoms and compute first-shell coordination numbers, C-C bond lengths, and C-C-C bond angles. Confirm if the structure decomposes into two FCC sublattices shifted by (1/4, 1/4, 1/4) where every atom of sublattice A is bonded to four equidistant atoms of sublattice B at the tetrahedral angle
