Two tri(2-chlorobenzyl)tin(IV) complexes with dithiocarbamate ligands (2-Cl- C6H4CH2)3SnS2CN(C5H10) 1 and (2-Cl-C6H4CH2)3SnS2CN(C4H9N) 2 have been synthesized by the reaction of tri(2-chlorobenzyl)tin(IV) chloride with dithiocarbamates and characterized by elemental analysis, IR and 1H NMR. The crystal structures were determined by X-ray single-crystal diffraction. The crystal of complex 1 belongs to triclinic, space group P with a = 9.121(5), b = 10.788(6), c = 15.549(8) ? a = 77.812(6), b = 88.279(8), g = 72.023(6)o, Z = 2, V = 1421.5(13) ?, Dc = 1.532 g/cm3, ?= 1.344 mm-1, F(000) = 660, R = 0.0382 and wR = 0.0984; and that of complex 2 is of monoclinic, space group P21/n with a = 13.892(10), b = 2.1274(8), c = 2.0553(15) ? b = 107.145(11)o, Z = 4, V = 2726(3) ?, Dc = 1.600 g/cm3, ?= 1.403 mm-1, F(000) = 1320, R = 0.0361 and wR = 0.0826.

Based on the entangled state representation and a bosonic phase operator formalism, we tackle with Cooperpair number-phase quantization for the inductance coupling circuit including Josephson junctions, and then investigate how Josephson current equations change due to the presence of the coupling inductance and obtain bosonic operator Faraday formula, as well as the corresponding number-phase uncertainty relation.
