Poly[bis-[?(4)-N-(2-hydroxy-imino-propion-yl)-N'-(2-oxidoimino-propion-yl)propane-1,3-diaminato]dimethano-lcalciumdicopper(II)].

ABSTRACT: In the title compound, [CaCu(2)(C(9)H(13)N(4)O(4))(2)(CH(3)OH)(2)](n), the Ca(II) atom lies on an inversion center and is situated in a moderately distorted octa-hedral environment. The Cu(II) atom is in a distorted square-pyramidal geometry, defined by four N atoms belonging to the amide and oxime groups of the triply deprotonated residue of N,N'-bis-(2-hydroxy-imino-propano-yl)propane-1,3-diamine (H(4)pap) and one oxime O atom from a neighboring Hpap ligand at the apical site, forming a dimeric [Cu(2)(Hpap)(2)](2-) unit. Each dimeric unit connects four Ca atoms and each Ca atom links four [Cu(2)(Hpap)(2)](2-) units through Ca-O(amide) bonds, leading to a three-dimensional framework. The crystal structure involves intra- and inter-molecular O-H?O hydrogen bonds.

trans-Bis[1,3-bis-(2-methoxy-phen-yl)triazenido]dimethano-lcadmium(II).

Project description:In the title compound, [Cd(C(14)H(14)N(3)O(2))(2)(CH(3)OH)(2)], each cadmium(II) center is six-coordinated by an N atom and an O atom of two 1,3-bis-(2-methoxy-phen-yl)triazene ligands and by the O atoms of two methanol mol-ecules. The distorted octa-hedral coordination geometry of the Cd atom has two N and two O atoms in the equatorial plane, and two O atoms in axial positions. The complex is stabilized by intra-molecular O-H?O and O-H?N hydrogen bonds. In the crystal structure the complexes are linked into chains via inter-molecular C-H?? stacking inter-actions. One of the methanol C atoms is disordered with ouccupancies of 0.7:0.3.

Project description:The title Cu(II) coordination polymer, {[Cu(C(7)H(10)N(6))(2)(H(2)O)(2)](NO(3))(2)·H(2)O}(n), was obtained by the reaction of equimolar Cu(NO(3))(2)·4H(2)O and 1,3-bis-(1,2,4-triazol-1-yl)propane (btp) in a water-methanol solvent. The Cu(II) atom is located on a centre of inversion and has an elongated octa-hedral coordination geometry formed by four N atoms from four symmetry-related btp ligands and two coordinated water mol-ecules. Adjacent Cu(II) atoms are connected by btp ligands, generating a double-stranded chain. The nitrate anion is disordered over two positions in a 0.828?(7):0.172?(2) ratio.

Project description:The title complex, [CdCl(2)(C(9)H(12)N(4))](n), is characterized by the formation of a zigzag chain structure parallel to [001]. In the chain, the Cd(2+) cation is coordinated by four bridging Cl(-) ligands in equatorial positions and two N atoms from symmetry-related and likewise bridging 1,3-bis-(imidazol-1-yl)propane ligands in axial positions, forming a distorted CdCl(4)N(2) octa-hedron.

catena-Poly[[[bis-[2,2'-(propane-1,3-diyl-dithio)bis-(1,3,4-thia-diazole)-?N]copper(II)]-bis-[?-2,2'-(propane-1,3-diyldithio)bis-(1,3,4-thia-diazole)-?N:N]] bis-(perchlorate)].

Project description:In the title compound, {[Cu(C(7)H(8)N(4)S(4))(4)](ClO(4))(2)}(n), the Cu(II) atom, occupying a crystallographic inversion centre, is six-coordinated by six N atoms of three symmetry-related 2,2'-(propane-1,3-diyldithio)bis-(1,3,4-thia-diazole) (L) ligands in a slightly distorted octa-hedral geometry. The ligand L adopts two kinds of coordination modes in the crystal structure; one is a monodentate coordination mode and serves to complete the octa-hedral coordination of the Cu atom and the other is an N:N'-bidentate bridging mode in a trans configuration, bridging Cu atoms via translation symmetry along the b axis into a chain structure. The perchlorate ions serve as acceptors for inter-molecular C-H?O hydrogen bonds, which link the chains into a three-dimensional network.

Sulfonated 1,3-bis-(4-pyrid-yl)propane.

Project description:In the title compound, 4-[3-(3-sulfonato-pyridin-1-ium-4-yl)prop-yl]pyridin-1-ium-3-sulfonate, C(13)H(14)N(2)O(6)S(2), the mol-ecule is zwitterionic, with the sulfonic acid proton transfered to the basic pyridine N atom. Also, the structure adopts a butterfly-like conformation with the sulfonate groups on opposite sides of the 'wings'. The dihedral angle between the two pyridinium rings is 83.56?(7)°, and this results in the mol-ecule having a chiral conformation and packing. There is strong inter-molecular hydrogen bonding between the pyridinium H and sulfonate O atoms of adjoining mol-ecules. In addition, there are weaker inter-molecular C-H?O inter-actions.

Poly[propane-1,3-diammonium [cuprate(II)-bis-(?(2)-pyridine-2,3-dicarboxyl-ato)] trihydrate].

Project description:The title polymeric compound {(C(3)H(12)N(2))[Cu(C(7)H(3)NO(4))(2)]·3H(2)O}(n) or {(pnH(2))[Cu(py-2,3-dc)(2)]·3H(2)O}(n) (pn is propane-1,3-diamine and py-2,3-dcH(2) is pyridine-2,3-dicarboxylic acid), was synthesized by reaction of copper(II) chloride dihydrate with a proton-transfer compound, propane-1,3-diammonium pyridine-2,3-dicarboxyl-ate or (pnH(2))(py-2,3-dc), in aqueous solution. The anion is a six-coordinate complex (site symmetry ), with a distorted octa-hedral geometry around Cu(II), consisting of two bidentate pyridine-2,3-dicarboxyl-ate groups and two O atoms of bridging ligands from (py-2,3-dc)(2-) fragments, which are located in trans positions. The (pnH(2))(2+) cation is disordered over two sites by the center of inversion. Inter-molecular hydrogen bonds, ?-? [centroid-centroid distances of 3.539?(3)?Å] and C-O?? stacking inter-actions [O?Cg = 3.240?(5)?Å; Cg is the center of the pyridine ring], connect the various components into a supra-molecular structure.

trans-Diaqua-bis{1,3-bis-[5-(2-pyrid-yl)-2H-tetra-zol-2-yl]propane}zinc(II) bis-(perchlorate).

Project description:The Zn(II) ion in the title compound, [Zn(C(15)H(14)N(10))(H(2)O)(2)](ClO(4))(2), lies on a centre of symmetry. The distorted N(4)O(2) octa-hedral coordination environment around the Zn atom is composed of two 1,3-bis-[5-(2-pyrid-yl)-2H-tetra-zol-2-yl]propane ligands (L1) and two water mol-ecules, coordinated in trans positions. The ligand acts as a typical bidentate chelating ligand through one of its 2-pyridyl-2H-tetra-zole units, forming a five-membered Zn-N-C-C-N metallacycle with a small N-Zn-N bite angle [77.40 (8)°]. The other 2-pyridyl-2H-tetra-zole unit remains uncoordinated. The average Zn-N distance (2.156 Å) is somewhat longer than the distance between the Zn(II) center and the aqua ligand [2.108 (2) Å]. The coordinated pyrid-yl-tetra-zoyl rings are quasi-coplanar, making a dihedral angle of 1.9 (2)°, while the uncoordinated rings show a larger inter-planar angle of 21.3 (2)°. The flexible propane spacer displays a zigzag chain. Inter-molecular O-H⋯N and O-H⋯O inter-actions result in two-dimensional polymeric structures parallel to (100). Two C atoms of the spacer are disordered over two positions, with site occupancy factors of ca 0.85 and 0.15.

Project description:In the title compound, [Co(C(16)H(14)N(4)O)(2)](C(6)H(2)N(3)O(7))(2)·3CH(3)CN, the Co(II) ion is located on a crystallographic twofold rotation axis and is coordinated in a slightly distorted tetra-hedral environment by four N atoms from the two bidentate N-heterocycles. The crystal structure is stabilized by inter-molecular N-H?O and N-H?N hydrogen bonds. One of the acetonitrile solvent mol-ecules also lies on a twofold rotation axis.

Diazido-bis(propane-1,3-diamine)copper(II).

Project description:In the title complex, [Cu(N(3))(2)(C(3)H(10)N(2))(2)], the Cu(II) ion resides on a centre of symmetry and is in a Jahn-Teller distorted octa-hedral coordination environment comprising two N atoms from azide anions in axial positions and four N atoms from propane-1,3-diamine (tn) ligands in equatorial positions. Inter-molecular N-H?N hydrogen bonds produce R(2) (1)(6), R(2) (2)(8), R(2) (2)(12) and R(4) (2)(8) rings, generating a two-dimensional layer.
