The dataset includes 300 continuous cyclic voltammetry (CV) scans and differential pulse voltammetry (DPV) measurements, which were used to evaluate the electrochemical stability, oxidation/reduction behavior, and frontier molecular orbital energy levels of the Pt(II) complexes. Electrochemical properties of PtN5N1 and PtN5N2. 300 continuous cyclic voltammogram (CV, A B) and differential pulse voltammetry (DPV, C D) of PtN5N1 and PtN5N2 in anhydrous N, N-dimethylformamide (DMF) under nitrogen atmosphere.

Variables

• Current (A) – Measured electrochemical current during CV or DPV measurements, expressed in amperes.

  Oxidation peak potential (V) – Potential corresponding to the oxidation process of the Pt(II) complex.

  Reduction peak potential (V) – Potential corresponding to the reduction process of the Pt(II) complex.

  DPV current (A) – Current response recorded during differential pulse voltammetry measurements.

File: Single-crystal.zip

Description: This compressed file contains single-crystal X-ray crystallographic data for PtN5N1 and PtN5N2. The dataset includes crystallographic information files (.cif) and corresponding checkCIF validation reports for each Pt(II) complex. These files provide structural information used to confirm the molecular geometry, coordination environment, and crystal structure quality of PtN5N1 and PtN5N2.
