چکیده
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.

In the title compound, [Cd(2)(C(6)H(8)O(4))(2)(C(16)H(20)N(4))(H(2)O)(4)](n), penta-gonal-bipyramidally coordinated Cd(II) ions are connected into {Cd(2)(2,2-dimethyl-succinate)(2)(H(2)O)(4)} centrosymmetric dimeric clusters. In turn, these clusters are linked by tethering 1,4-bis-(3-pyridylmeth-yl)piperazine (3-bpmp) ligands into [Cd(2)(2,2-dimethyl-succinate)(2)(3-bpmp)(H(2)O)(4)](n) coordina...

In the title compound, [ZnCl(2)(C(16)H(20)N(4))](n), tetra-hedrally coordinated divalent Zn atoms are ligated by two Cl atoms and two N-donor atoms from two 1,4-bis-(3-pyridylmeth-yl)-piperazine (3-bpmp) ligands. The tethering 3-bpmp ligands promote the formation of [ZnCl(2)(3-bpmp)](n) chains situated parallel to (02). These chains aggregate via C-H⋯Cl inter-actions to form supra-molecular lay...

In the title compound, {(C4H12N2)2[Li2(P6O18)]·4H2O} n , the phosphate ring anion, located around an inversion center, adopts a chair conformation. Adjacent P6O18 rings are linked via corner-sharing by LiO4 tetra-hedra, generating anionic porous {[Li2(P6O18)](4-)} n layers parallel to (101). The piperazine-1,4-diium cations occupy the pores and develop hydrogen bonds with the inorganic framewor...

The crystal structure of the title compound, (C(5)H(14)N(2))[ZnCl(4)]·0.5H(2)O, is built up from discrete 1-methyl-piperazine-diium cations with chair conformation, tetrahedral tetrachloridozincate anions and uncoordinated solvent water mol-ecules linked together by three types of inter-molecular hydrogen bonds, viz. N-H⋯Cl, N-H⋯O and O-H⋯Cl.

In the title compound, {[Cu(C(10)H(14)N(4))(2)(H(2)O)(2)](NO(3))(2)}(n), the Cu(II) ion lies on an inversion center and is six-coordinated in an octa-hedral environment by four N atoms from four different 1,1'-butane-1,4-diyldiimidazole ligands and two O atoms from the two water mol-ecules. Bridging by the ligands results in a ribbon structure. Adjacent ribbons are linked to the nitrate anions ...
