Poly[1,4-bis-(4-pyridylmeth-yl)piperazine-diium [[tetra-aqua-cobaltate(II)]-?-pyromellitato-?O:O] dihydrate].

ABSTRACT: In the title compound, {(C(16)H(22)N(4))[Co(C(10)H(2)O(8))(H(2)O)(4)]·2H(2)O}(n), the octa-hedrally coordinated Co(II) atom is situated on an inversion center and possesses four aqua ligands. The Co atoms are linked into an anionic coordination polymer chain by bis-monodentate pyromellitate ligands. The chain motifs are connected into a supra-molecular layer by hydrogen bonding mediated by uncoordinated water mol-ecules. Charge balance is provided by doubly protonated bis-(4-pyridylmeth-yl)piperazine units, which are anchored to the coordination polymer chain motifs by N-H?O hydrogen bonding.

catena-Poly[[[tetra-aqua-magnesium]-trans-?-[(piperazine-1,4-diium-1,4-di-yl)bis-(methyl-ene)]di-phospho-nato] hemihydrate].

Project description:The structure of the title polymer, }[Mg(C6H14N2O6P2)(H2O)4]·0.5H2O} n , is based on centrosymmetric MgO6 octahedra, which are linked by [(piperazine-1,4-diium-1,4-di-yl)bis-(methyl-ene)]di-phospho-nate ligands, forming chains parallel to [1-1-1]. These chains are connected via hydrogen bonds primarily formed between the phospho-nate groups and water mol-ecules. The latter constitute four of the corners of the MgO6 polyhedra and bind to the O atoms of the phospho-nate groups of neighbouring chains. The lattice water molecule is disordered around an inversion centre, exhibiting an occupancy of 0.25.

Piperazine-1,4-diium bis-(pyridine-2,6-dicarboxyl-ato-?O,N,O)cobaltate(II) tetra-hydrate.

Project description:The asymmetric unit of the title complex, (C(4)H(12)N(2))[Co(C(7)H(3)NO(4))(2)]·4H(2)O, consists of one piperazinediium dication, one [Co(py-2,6-dc)(2)](2-) dianion (where py-2,6-dc is pyridine-2,6-dicarboxyl-ate) and four water mol-ecules.

In the crystal, inter-molecular O-H?O, N-H?O and weak C-H?O hydrogen bonds link the components, forming a three-dimensional network.

Project description:In the title compound, [Cu(C(8)H(4)O(4))(C(16)H(20)N(4))(H(2)O)](n), square-pyramidally coordinated Cu(II) ions are linked into [Cu(H(2)O)(isophthalate)](n) coordination polymer chains by isophthalate dianions.

The pseudo three-dimensional structure of the title compound is fostered by inter-layer O-H?O hydrogen bonding between the aqua ligands and unligated isophthalate O atoms. The selected crystal was non-merohedrally twinned. Only reflections from the major twin component were used in the solution and refinement.
