Crystal Structure of catena-Poly[diaquabarium(II)-μ-aqua-κ²O:O-di-μ-1-oxopyridinium-2-thioacetato-κ⁴ O:O trihydrate]

Abstract

catena-Poly[diaquabarium(II)-μ-aqua-κ²O:O-di-μ-1-oxopyridinium-2-thioacetatao-κ⁴O:O trihydrate], [Ba(C₇H₆O₃NS)₂^-(H₂O)₃]_n·3nH₂O was synthesized and the crystal structure was determined by a single-crystal X-ray diffraction method. The title complex crystallizes in orthorhombic space group P2₁2₁2₁ with unit-cell parameters a = 7.7217(1)Å, b = 14.4052(2)Å, c = 19.9285(2)Å, V = 2216.70(5)ų. The final R value is 0.0143 for 3179 measured reflections. The central barium(II) metal makes coordination with ten oxygen atoms, and forms a polymeric chain by Ba-O-Ba links in the crystal.
