Powder second-harmonic generation (SHG) efficiencies are usually measured at single wavelengths. In the present work, we provide a proof of concept of spectrally resolved powder SHG measured for a newly obtained series of three non-centrosymmetric coordination polymers (CPs). CPs are constructed from tetrahedral linker鈥搕etraphenylmethane-based tetraphosphonate octaethyl ester and cobalt(II) ions of mixed, octahedral (O_h), and tetrahedral (T_d), geometries and different sets of donors (CoO₆ vs CoX₃O). Isostructurality of the obtained materials allowed for the determination of anion-dependent tunability of SHG optical spectra and their relationship with solid-state absorption spectra.
