Abstract
The title complex Ca(L)2(H2O)5 [HL=salicylaldehyde-4-aminobenzene sulfonic acid] was synthesized by the reaction of calcium perchlorate with salicylaldehyde-4-aminobenzene sulfonic acid in the CH3CH2OH/H2O. It was characterized by elemental analysis, IR and X-ray diffraction single crystal structure analysis. The crystal of the title complex [Ca(H2O)5(C13H10NO4S)2] belongs to orthorhombic, space group Pca21 with a=1.162 47(18) nm, b=0.725 91(10) nm, c=3.516 3(3) nm, V=2.967 3(7) nm3, Z=4, Dc=1.528 Mg·m-3, μ=4.22 mm-1, F(000)=1 424, and final R1=0.044 2, wR2=0.098 3. The complex comprises a seven-coordinated calcium(Ⅱ) center, with a O7 distorted pengonal bipyramidal coordination environment. The molecules are connected by hydrogen bonds to form two dimensional layered structure. CCDC:658852.
