Synthesis and X‐ray structure studies of complex [Cu(o‐phenanthroline)2 (saccharin)] · (saccharin) · 2 H2O

The title compound has been synthesized and its crystal structure determined at room temperature, Mr = 824.34, triclinic, space group P–1(2), a = 13.622(4), b = 13.770(4), c = 11.167(3) A; α = 104.83(2), β = 110.01(2), γ = 62.04(2) degree; U = 1727.0(9) A3, Z = 2, Dcalc = 1.59 g/cm3. The final R is 0.066 for 3299 independent observed reflections with I ≧ 3σ(I). The crystal structure consists of repeated [Cu(o-phen)2(sac)]+ cations, non-coordinated saccharin anion and two lattice water. And the central ion Cu2+ forms a trigonal-bipyramidal stereochemistry.
