Luminescence from K2Pd(SCN)(4), [K( 18-crown-6)](2)Pd(SCN)(4), and (2-diethylammonium N-(2,6-dimethylphenyl)acetamide)(2)Pd(SCN)(4) is observed between 10000 and 14500 cm(-1) (1000 and 690 nm) at temperatures below 100 K. Luminescence lifetimes of up to 4.15 ms are measured at 10 K. The spectra show resolved vibronic progressions with average energy intervals of 278 and 150 cm(-1). The average Stokes shift determined from the luminescence and excitation spectra is 4100 cm(-1). Average dimensionless emitting-state distortions Delta of 3.75 and 1.7, corresponding to Huang-Rhys parameters S of 7.0 and 1.5, along the two modes are obtained from calculated luminescence spectra.
