Crystal structure, Z-scan measurements and theoretical calculations of third-order nonlinear optical properties of tetrachloro(1,10-phenanthroline-N,N′)tin(IV)

A tin(IV) complex constructed by 1,10-phenanthroline: tetrachloro(1,10-phenanthroline-N,N′)tin(IV) has been synthesized. Its crystal structure has been determined by means of X-ray single crystal diffraction, the tin(IV) atom is six-coordinate in a distorted octahedral geometry, intermolecular CH···Cl hydrogen bonds lead to the formation of a double chains along [1 0 1]. Its thermal stability was determined by TGA/DSC. Its second hyperpolarizability γ value was determined to be 6.2 × 10−58 C m4/V3 by Z-scan technique with 20 picosecond (ps) pulses at wavelength 1064 nm. Theoretical calculations of its γ value were performed by MOPAC2012 program and the calculated value is in good agreement with the experimental value.
