The phrase "a flat conformation" is correct and usable in written English.
It can be used in contexts related to chemistry, biology, or structural analysis where the shape or arrangement of a molecule or structure is being described.
Example: "The compound exhibits a flat conformation, which is crucial for its interaction with other molecules."
Alternatives: "a planar structure" or "a flat structure".
The cohesive energy could be markedly reduced by the C-substitution, which becomes −5.52 eV for the c-germanyne with a flat conformation.

In general, the protein matrix could have a considerable influence on the bending angle of the latter and thereby affect the redox potential of FAD; a flat conformation of FAD (0 10°) favors the oxidized state and a bent "butterfly" conformation (15 30°) favors the reduced state.
Amide NH protons are displaced by the metal during the formation of these tight complexes in which the main chain atoms adopt a flat conformation (φ = 180°, ψ = 0°), as in Fig 1h.
Macrocycle 1 and dimer 2 adopt a flat conformation,[ 35] whereas a helical conformation is adopted by tetramers 3 and 5 (1.5 turns) and octamer 4 (over three turns).
However, for the SLG model the difference between the total energy of a bent structure (2f) and a flat sheet (2b) is positive Δ Et = 2017 kJ/mol, which indicates that the planar SLGO structure (2a) is less stable than bent SLGO (2e), and SLG is more stable in a flat conformation (2b).
Because some steroids exhibit identical functional groups and different conformational structure, we also postulate that the flat conformation of a pregnanesteroid determines its Na+-retaining capacity in vivo.
For c-germanyne, its flat conformation has a similar electronic property to c-silicyne as shown in the inset of Figure 4c.
Unlike the bent FMN ring structures present in most NTR complexes currently known, the flavin system in the Ec_ydjA structure maintains a flat ring conformation, which is sandwiched between a Trp and a His residue from each monomer.
From the surface tension data a flat molecular conformation was evident at 1×10−3 mol dm−3 (131 Å2 surface area), which we assumed to correspond to the low aggregation number of premicellar aggregates.
However, the flat conformation is dynamically unstable with a negative frequency about −150 cm −1 in the reciprocal space as shown in Figure 2a.
