Single crystals of dimethyl [(4-nitrophenyl)sulfonyl]amidophosphate (HL¹) and its coordination compounds with Yb³⁺ and La³⁺ have been obtained. Their physicochemical properties using X-ray diffraction analysis, absorption (300 K and 5 K), emission (300 K and 77 K) and FTIR spectroscopy, thermogravimetry, differential scanning calorimetry, magnetization measurements have been determined and compared with those of Na[Ln(L²)₄], where HL² = dimethyl (4-methylphenylsulfonyl)amidophosphate Ln = La³⁺, Yb³⁺, Gd³⁺. The effect of substitution of a methyl group at the para position by a nitro group on structural (Yb–O distances, coordination polyhedra, non-covalent interactions, packing), spectroscopic (²F_7/2 and ²F_5/2 crystal field splitting, radiative lifetime (τ_rad), emission decay time (τ), intrinsic quantum yield (QYb Yb), antenna effect) and magnetic properties in DC and AC fields were analyzed.
