Abstract A new metal-organic coordination polymer, [Pb(L)(adip)0.5] (1) was synthesized under hydrothermal conditions by using 1-(1H-imidazo[4,5-f][1,10]phenanthrolin-2-yl)naphthalen-2-ol (HL) and adipic acid (H2adip). The complex 1 was characterized by diffraction and elemental analyses. In complex 1, the binuclear [Pb2L2] units were formed by the OH-deprotonation bridging neighboring Pb(II) atoms, and the adipate linked the binuclear [Pb2L2] units to form a symmetric one-dimensional chain. The 1D chain was further extended to the 2D supramolecular layer structure through π-π interactions between the L ligands.

Abstract The new ternary one-dimensional chain compounds K2ZrS4 , Rb2ZrS4 and Rb2HfS4 were prepared at 350 °C by reacting A2S3 and S with elemental M (A = K, Rb; M = Zr, Hf). They are isostructural, crystallizing in the orthorhombic space group Pbca with Z = 8 . The M atoms are in a distorted octahedral environment of four S2− anions and one S22− unit. The structure consists of infinite anionic chains comprised of edge-sharing M S6 octahedra running parallel to the [001] direction separated by the alkali metal cations. The composition of the chain may be formulated as 1∞[MS4/ 2 (S2)2−]. The two crystallographically independent alkali cations are in eight-and ninefold coordination of S atoms.
