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]

In the title compound, [Co(C15H11N2O2)2(C2H4O2(C4H12N3)], the CoIII atom exhibits a distorted octa­hedral coordination geometry. There are inter­molecular N—H⋯O hydrogen bonds, forming a three-dimensional network. [ABSTRACT FROM AUTHOR]

In the title compound, C17H16N2, the 1,4-diazepine ring adopts a distorted boat conformation, in which the sum of the inter­nal angles is 809°. The mol­ecules are linked by a pair of C—H⋯N hydrogen bonds into a C22(14) chain along the [10 ] direction. [ABSTRACT FROM AUTHOR]

The coordination polyhedron in the title compound, [Bi(C15H14NS2)3] or [Bi{S2CN(C7H7)2}3], is a distorted trigonal anti­prism, with three strong (2.664–2.731 Å) and three weak (2.904–2.965 Å) Bi—S bonds. [ABSTRACT FROM AUTHOR]
