The new tetracarbonyl — chromium-triphenyl phosphine complex was synthesized and characterized using ultraviolet (UV)–visible, Fourier transform infrared (FTIR), and nuclear magnetic resonance (NMR) techniques. The characterization results confirm the molecular structure of the new complex. The z-scan measurements were done by diode laser [continuous wave (CW)] to estimate the nonlinear optical parameter (χ 3). The results led to calculate three parameters: the ground-state cross sections (), the excited-state cross sections (), and thermo–optic coefficient of the new complex. This study indicated that our complex is a suitable for photonic applications.
