The results show that the complex belongs to the monoclinic system with the space group of P21 / c, the unit cell parameters are: a = 0.9719 (2) nm, b = 2.5521 (5) nm, c = 1.2505 93.407 (5) °, V = 3.096 (1) nm3, Z = 4, Dc = 1.553 g / cm3, μ = 0.978 mm-1, F (000) = 1484. Copper complexes in the metal with two phenanthroline coordination, but also with a Cl anion coordination. The phenylsulfonyl taurate anion forms a one-dimensional helical chain through NH ... O hydrogen bonds, and the cation forms a one-dimensional chain by π-π stacking. The adjacent one-dimensional chain then forms a two-dimensional network by π-π stacking, Two-dimensional network between the balanced insertion of phenylthionyl taurine anion to build one-dimensional helical chain, the distance between adjacent helical strands of 0.972 (1) nm, the helical chain and the two-dimensional network through the weak and rich in CH ... O hydrogen bonds form a three-dimensional network structure.
