struc·tur·al formula

(strŭk′chər-əl)
A chemical formula that shows how the atoms making up a compound are arranged within the molecule. For example, the structural formula of aspirin is CH3COOC6H4COOH, indicating that it is an acetate (CH3COO) of a phenyl (C6H4) organic acid (COOH). Since structural formulas can get quite long, formulas are usually given with all the atoms totaled up instead (in this case, C9H8O4). Compare molecular formula.
