Reaction of copper(I) chloride or bromide with equimolar amounts of the neutral pyrimidine-2-thione ligand (pymtH) afforded linear chain polymers [Cu(pymtH)X]n (X = Cl, Br) with the pymtH ligand acting as a bridging N, S donor. In contrast, copper(I) iodide under the same conditions gave the dimeric complex [Cu(pymtH)2I]2 with the pymtH ligand adopting(More)
A Zn(II)-MOF [Zn(2)(tzba)(DMF)]·0.5DMF (1) (H(2)tzba = 4-(1H-tetrazol-5-yl) benzoic acid, DMF = N,N'-dimethylformamide) has been solvothermally synthesized and characterized. 1 is a three-dimensional (3D) microporous framework possessing an unusual multi-nodal (3,3,6)- or (4,4,4,4)-connected topological net. The small-sized pores, open metal sites, phenyl π(More)

The asymmetric unit of the title compound, [Co(C(12)H(6)N(2)O(2))(H(2)O)(4)](NO(3))(2), consists of a Co(II) complex cation with twofold rotational symmetry and two nitrate anions. The Co(II) atom has a distorted octa-hedral geometry with the basal plane occupied by two 1,10-phenanthroline-5,6-dione N atoms and two aqua O atoms, with the other two aqua(More)

Reaction of 4'-phenyl-2,2':6',2''-terpyridine (phtpy), copper acetate hydrate and ammonium thio-cyanate under solvothermal conditions led to the formation of the title compound, {[Cu(C(21)H(15)N(3))(2)][Cu(2)(NCS)(4)]}(n). The structure is composed of discrete [Cu(phtpy)(2)](2+) cations and polymeric anionic {[Cu(SCN)(2)](-)} chains propagating along [010].(More)
Three new coordination polymers, [Ag4(H2bpz)4(SO4)2]·H2O (1), [Ag2(H2bpz)2(SO4)]·3H2O (2), and [Ag3(H2bpz)4](SO4)2/3(OH)5/3·4H2O (3) have been solvothermally synthesized with Ag2SO4 and flexible ligand 3,3',5,5'-tetramethyl-4,4'-bipyrazole (H2bpz) in different solvents and temperatures. Complex 1 is a 2-fold interpenetrated three-dimensional (3D) framework(More)

In the title salt, catena-poly[[[aquacopper(II)]-mu-3-(2-pyridylmethyleneamino)propanoato-kappa4N,N',O:O'] perchlorate], {[Cu(C9H9N2O2)(H2O)]ClO4}n, the monomeric unit contains a square-based pyramidal Cu(II) centre. The four basal positions are occupied by a tridentate anionic Schiff base ligand which furnishes an NNO-donor set, with the fourth basal(More)

The title compound, {[Cu(C(20)H(14)N(4))(2)][Cu(2)(NCS)(4)]}(n), was obtained by reacting copper acetate hydrate, ammonium thio-cyanate and 4'-(3-pyrid-yl)-2,2':6',2''-terpyridine (3-pytpy) under solvothermal conditions. The polymeric complex is isostructural with the 4'-phenyl-2,2':6',2''-terpyridine (phtpy) analogue. All intramolecular distances and(More)
The reaction of N-rich pyrazinyl triazolyl carboxyl ligand 3-(4-carboxylbenzene)-5-(2-pyrazinyl)-1H-1,2,4-triazole (H2 cbptz) with MnCl2 afforded 3D cationic metal-organic framework (MOF) [Mn2 (Hcbptz)2 (Cl)(H2 O)]Cl⋅DMF⋅0.5 CH3 CN (1), which has an unusual (3,4)-connected 3,4T1 topology and 1D channels composed of cavities. MOF 1 has a very polar framework(More)
