C24H2oCl2Cu2N4Na204, triclinic, PI (No. 2), a = 8.366(2) Ä, b = 8.832(3) Ä, c = 9.410(3) Ä, α = 101.75(2)°, β = 100.83(2)°, γ = 105.18(2)°, V = 635.2 Χ 3 , Z= 1, RgdF) = 0.065, wRteffF 2 ) = 0.148, T= 293 K. Source of materialUnder continuous stirring, 0.43 g (2.52 mmol) copper dichloride dihydrate (CuCh · 2H2O), 0.5 g (2.52 mmol) 1,10-phenanthroline monohydrate (C12H8N2 · H2O) and 0.33 g (2.52 mmol) glutaric acid (HOOC(CH2)3COOH) were successively added to 50 ml CH3OH/H2O (1:1 v/v), leading to a greenish slurry. After being filtered, the residual greenish slurry in the filter was then washed with a concentrated Na2CC>3 solution and a blue filtrate was collected. A small amount of blue crystals were grown by slow evaporation at room temperature for several weeks. DiscussionThe crystal structure of the title compound consists of Na + cations, hydrogen bonded OH -anions and dinuclear [CU2CI2 (phen)2(OH)2] complex molecules centered at the crystallographic Id positions. The Cu atoms are penta-coordinated by one bidentate chelating phenanthroline ligand, two bridging hydroxide groups and one CI atom to form a distorted square pyramid with two phen Ν atoms ant two hydroxide Ο atoms at the basal positions and the CI atom at the apical position (
