Abstract:Abstract Two sulfato Cu II complexes [Cu 2 (bpy) 2 (H 2 O)(OH) 2 (SO 4 )]· 4H 2 O ( 1 ) and [Cu(bpy)(H 2 O) 2 ]SO 4 ( 2 ) were synthesized and structurally characterized by single crystal X—ray diffra...Abstract Two sulfato Cu II complexes [Cu 2 (bpy) 2 (H 2 O)(OH) 2 (SO 4 )]· 4H 2 O ( 1 ) and [Cu(bpy)(H 2 O) 2 ]SO 4 ( 2 ) were synthesized and structurally characterized by single crystal X—ray diffraction. Complex 1 consists of the asymmetric dinuclear [Cu 2 (bpy) 2 (H 2 O)(OH) 2 (SO 4 )] complex molecules and hydrogen bonded H 2 O molecules. Within the dinuclear molecules, the Cu atoms are in square pyramidal geometries, where the equatorial sites are occupied by two N atoms of one bpy ligand and two O atoms of different μ 2 —OH groups and the apical position by one aqua ligand or one sulfato group. Through intermolecular O—H···O and C—H···O hydrogen bonds and intermolecular π—π stacking interactions, the dinuclear complex molecules are assembled into layers, between which the hydrogen bonded H 2 O molecules are located. The Cu atoms in 2 are octahedrally coordinated by two N atoms of one bpy ligand and four O atoms of two H 2 O molecules and two sulfato groups with the sulfato O atoms at the trans positions and are bridged by sulfato groups into 1 [Cu(bpy)(H 2 O) 2 (SO 4 ) 2/2 ] chains. Through the interchain π—π stacking interactions and interchain C—H···O hydrogen bonds, the resulting chains are assembled into bi—chains, which are further interlinked into layers by O—H···O hydrogen bonds between adjacent bichains.Read More
