A series of substituted 2-hydroxysalicylidenebenzohydrazides were converted into their diorganotin complexes in good yields upon reaction with di-n-butyl or diphenyltin. All organtotin compounds were full characterized by NMR (1H, 13C, and 119Sn), UV, IR, and mass spectrometry. The X-ray structures of four complexes showed the tin atoms with trigonal bipyramidal geometry. The 119Sn parameters for 1-4 indicate pentacoordinated tin centers. The photophysical properties of organotin compounds exhibit quantum yields below 5 % with lifetimes in the range 10-10-10-11s. Preliminary results by confocal microscopy fluorecent imagen of B16F12 cells in the present of 2 showed yellow fluorescent after being for 2 hours and reveals its potential applications as a fluorescent imaging material.
