Catena-Poly[[tripyridine-nickel(II)]-?-5-bromo-isophthalato].

ABSTRACT: The title compound, [Ni(C(8)H(3)BrO(4))(C(5)H(5)N)(3)], is the first structurally characterized complex with a transition metal coordinated by a 5-bromo-isophthalate anion. The Ni(II) ion is coordinated by three O atoms from the carboxyl-ate groups and three N atoms from three pyridine ligands in a distorted octa-hedral coordination geometry. The 5-bromo-isophthalate anion is planar within 0.057?(2)?Å. The two carboxyl-ate groups of the ligand coordinate the Ni(II) ions in a chelating and monodentate mode, linking the metal atoms into infinite chains along the [010] direction. These chains are stacked together via strong ?-? inter-actions between the pyridine rings [centroid-centroid distance 3.601?(4)?Å], forming a three-dimensional motif.

Project description:In the crystal structure of the title polymeric compound, [Cu(C(12)H(12)O(4))(C(10)H(8)N(2))](n), the asymmetric unit consists of one Cu(II) ion, one 5-tert-butyl-isophthalate (tbip) and one 2,2'-bipyridine (bpy) ligand. The copper(II) ion is four-coordin-ated by two N atoms from bipy and two O atoms from two tbip ligands, leading to a distorted tetrahedral coordination. Each tbip ligand adopts a bis-monodentate coordination mode to connect two symmetry-related copper(II) ions, so forming a zigzag polymer chain parallel to [001]. The tert-butyl methyl groups are disordered over two positions with occupancies of 0.506?(6)/0.494?(6).

catena-Poly[[aqua-(2,2'-bipyridyl)cobalt(II)]-μ-5-nitro-isophthalato].

Project description:In the crystal structure of the title compound, [Co(C(8)H(3)NO(6))(C(10)H(8)N(2))(H(2)O)](n), there are two symmetry-independent one-dimensional coordination polymers, which are approximately related by noncrystallographic inversion symmetry. Each zigzag chain is constructed from one Co(II) ion, one O-monodentate 5-nitro-isophthalate (ndc) dianion, one N,N'-bidentate 2,2'-bipyridyl ligand and one water mol-ecule. A symmetry-generated O,O'-bidentate ndc dianion completes the cobalt coordination environment, which could be described as very distorted cis-CoN(2)O(4) octa-hedral. The bridging ndc ligands result in parallel chains running along the a direction, and O-H⋯O hydrogen bonds arising from the water mol-ecules complete the structure.
