The title coordination polymer, {[Cu2(C6H15N2O)2(C10H8N2)](ClO4)2} n, was synthesized from 4,4′-bipyridine, N-hydroxypropyl-1,3-propanediamine and copper(II) per­chlorate. Structural analysis shows that each copper ion is coordinated by the 4,4′-bipyridine mol­ecule through one N atom, and by two N-hydroxypropyl-1,3-propanediamine ligands through the O atom and two N atoms of one, and the O atom from the second, giving a distorted square-pyramidal geometry. There are centres of inversion at the mid-points of the Cu2O2 ring and the bridging ligand. [ABSTRACT FROM AUTHOR]

The title compound, [Ag2Cl2(C26H30B10P2)2]·2CH2Cl2, was synthesized by the reaction of 1,2-bis­(dipenylphosphino)-1,2-dicarba- closo-dodeca­borane with AgCl in ethanol. The diphos­phino- closo-carborane ligand is coordinated in a bidentate manner to the Ag atom through the two P atoms. The coordination of the Ag atom is distorted tetra­hedral, in which two vertices are formed by one chelating diphosphine ligand, and the other two are occupied by two bridging Cl atoms. The molecule is centrosymmetric. [ABSTRACT FROM AUTHOR]
