The title compound, benzyl N-(ferrocenecarbonyl)glycinate,
[Fe(C₅H₅)(C₁₅H₁₄NO₃)], a glycine benzyl ester derivative, is an effective anion sensor for electrochemically sensing the dihydrogen phosphate anion (H₂PO₄-).
Intermolecular N--H...O hydrogen bonds form onedimensional
chains with graph set C(4) [N...O 2.811 (3)Å,]. A two-dimensional network is formed by linking the chains through Car--H...0=Cester interactions about inversion centres [graph set R²₂(14); C...O 3.406 (4)Å]. An intramolecular Ccp-H...0=Cester interaction
[C...O 3.540 (3)Å,] with graph set S(9) completes
the hydrogen bonding.
