Poly[tris-(?(3)-2-amino-ethane-sulfonato)-cobalt(II)potassium].

ABSTRACT: The title compound, [CoK(C(2)H(6)NO(3)S)(3)](n), is isotypic with its Ni(II) analogue. The Co(II) atom is chelated by the three taurinate ligands in a distorted octa-hedral geometry and in a facial manner. Each taurinate ligand bridges two K(+) ions via its sulfonate group, forming a three-dimensional framework. Weak N-H?O hydrogen bonding is observed in the crystal structure.

Project description:The hydro-thermally prepared title compound, [Co(C(2)H(6)NO(3)S)(2)](n), is isotypic with its Ni(II) analogue. The Co(II) cation is in a distorted octa-hedral environment, coordinated by four sulfonate O atoms and two N atoms from the taurine ligands. In comparison with the Ni(II) analogue, the Co-N and Co-O bonds are longer than the Ni-N and Ni-O bonds, whereas all other bond lengths and angles as well as the hydrogen-bonding motifs are very similar in the two structures. The sulfonate groups doubly bridge symmetry-related Co(II) atoms, forming polymeric chains along the a axis. N-H?O hydrogen bonding interactions consolidate the crystal packing.

Bis[2-(2-pyridylmethyl-amino)ethane-sulfonato-?N,N',O]zinc(II).

Project description:The title mononuclear complex, [Zn(C(8)H(11)N(2)O(3)S)(2)], is a zinc salt of 2-(2-pyridylmethyl-amino)ethane-sulfonic acid (Hpmt). The Zn(II) ion is located on an inversion centre and is octahedrally surrounded by four N and two O atoms. The deprotonated pmt(-) anion coordinates in a facial arrangement through its two N atoms and one of the sulfonate O atoms. The crystal packing is determined by inter-molecular N-H?O and C-H?O hydrogen bonds.

Poly[[diaqua-μ(2)-hydroxido-(μ(7)-2-phos-pho-nato-ethane-sulfonato)-dicopper(II)] trihydrate].

Project description:The crystal structure of the title compound, [Cu(2)(C(2)H(4)O(6)PS)(OH)(H(2)O)(2)]·3H(2)O, consists of two Cu(2+) ions, one (O(3)PC(2)H(4)SO(3))(3-) ion and one OH(-) ion, as well as five water mol-ecules, two of which are coordinated to Cu(2+). The Cu(2+) ions are coordinated by six O atoms. The CuO(6) polyhedra are connected by μ- and μ(3)-O atoms into zigzag chains along the b axis. These chains are further connected by -CH(2)CH(2)- groups to form layers, in turn building a three-dimensional framework via hydrogen bonding.

Tris(ethane-1,2-diamine-κN,N')cobalt(II) cis-aqua-2κO-μ-cyanido-1:2κC:N-hepta-cyanido-1κC-bis-(ethane-1,2-diamine-2κN,N')cobalt(II)molybdenum(IV) dihydrate.

Project description:The title compound, [Co(C(2)H(8)N(2))(3)][CoMo(CN)(8)(C(2)H(8)N(2))(2)(H(2)O)]·2H(2)O, is isostructural with the Ni(II) analogue. The Mo(IV) atom is coordinated by eight cyanide ligands, one of which forms a bridge to a Co(II) atom that is itself coordinated by two bidentate ethane-1,2-diamine (en) ligands and one water mol-ecule. Another Co(II) complex, coordinated to three bidentate en ligands, acts as the counter-ion. The crystal structure contains O-H⋯N/O, N-H⋯N/O and C-H⋯N/O hydrogen bonds, which form a three-dimensional network.

Poly[tris{μ(2)-4-[4-(di-methyl-amino)-phenyl-diazenyl]benzene-sulfonato}tri-dioxane-tri-sodium(I)].

Project description:The title compound, [Na(3)(C(14)H(14)N(3)O(3)S)(3)(C(4)H(8)O(2))(3)](n), is a polynuclear complex which includes, in the monomeric unit, three units of Na(I)-4'-dimethyl-amino-azobenzene-4-sulfonate [known as methyl orange (MO)] and three molecules of dioxane (C(4)H(8)O(2)). These constitute three kinds of Na(I) centres, two of which are seven-coordinate while the third is five-coordinate. One of the seven-coordinate centres is coordinated by six O atoms from the sulfonate groups of four different MOs and by one O atom from dioxane. The other is coordinated by seven O atoms from the sulfonate groups of five different MOs. The five-coordinate centre is coordinated by three O atoms from the sulfonate groups of three different MOs and two O atoms from two different dioxanes. In the crystal structure, a one-dimensional polymer chain is formed along the a axis and this ensures the thermal stability of the title compound. It is also to be noted that the N=N bond lengths of the three azo groups are appreciably different [1.259 (4), 1.196 (4), and 1.253 (4) Å].

Poly[(μ(3)-5-amino-isophthalato-κO,O':O'':O''')[μ(2)-1,2-bis-(4-pyrid-yl)ethane-κN:N']cobalt(II)].

Project description:In the title compound, [Co(C(8)H(5)NO(4))(C(12)H(12)N(2))](n), the Co(II) ion presents a distorted CoO(4)N(2) octa-hedral coordination geometry, formed by three 5-amino-isophthalate dianions and two 1,2-bis-(4-pyrid-yl)ethane ligands. One carboxyl-ate group of the 5-amino-isophthalate dianion chelates a Co cation and the other carboxyl-ate group bridges the other two Co cations, while the terminal N atoms of the 1,2-bis-(4-pyrid-yl)ethane ligand coordinate the neighboring Co cations, forming a two-dimensional polymeric architecture. Two pyridine rings of the 1,2-bis-(4-pyrid-yl)ethane ligand are twisted to each other with a dihedral angle of 50.94 (16)°. Weak C-H⋯O hydrogen bonding and N-H⋯π inter-actions are observed in the crystal structure. A void of 69 (5) Å(3) is present in the crystal structure, but no solvent mol-ecule can be located reasonably.
