چکیده
A novel 2D coordination polymer, [Mn(pyphen)(L)] (1) (L = 3-carboxy-1-(4′-(2′′carboxy)biphenylmethyl)-2-oxidopyridinium and pyphen = pyrazino[2,3f ][1,10]phenanthroline), has been synthesized under hydrothermal conditions, and characterized by elemental analysis, IR, UV/Vis spectra and its optical band gap. Crystal data for 1: C34H21MnN5O5, monoclinic, space group P21/c, a = 12.484(4), b = 13.473(5), c = 16.479(3) Å, β = 99.618(6)◦ , V = 2732.8(14) Å3, Z = 4. In 1, each L ligand coordinates to three Mn(II) atoms through its two carboxylate groups and one phenolate unit. In this way, L2− ligands link neighboring Mn(II) atoms to generate a layer structure.

The centrosymmetric binuclear title complex, [Mn(2)(C(8)H(5)NO(5))(2)(C(12)H(8)N(2))(2)(H(2)O)(4)]·2H(2)O, was obtained by the reaction of manganese chloride with 5-carb-oxy-1-carboxy-methyl-2-oxidopyridinium and 1,10-phenanthroline. The Mn(II) atom is coordinated by two N atoms from the 1,10-phenanthroline ligand, two O atoms from two 5-carboxyl-ato-1-carboxyl-atomethyl-2-oxidopyridinium ligan...

The title coordination polymer, {[Cd(2)(C(8)H(4)O(5))(2)(C(14)H(8)N(4))(2)]·2H(2)O}(n), has a layered structure. The asymmetric unit contains two Cd(II) ions, two pyrazino-[2,3-f][1,10]phenanthroline, two 5-hy-droxy-isophthalate (hip) ligands and two lattice water mol-ecules. Each Cd(II) ion is coordinated by two N atoms from a chelating pyrazino-[2,3-f][1,10]phenanthroline and four O atoms fro...

The title complex, [Co(C(5)H(2)N(2)O(4))(C(14)H(8)N(4))(2)]·2H(2)O, features a slightly distorted octa-hedral geometry for Co due to the sterical requirements of the orotic acid and pyrazino[2,3-f][1,10]phenanthroline ligands. Inter-molecular hydrogen bonding between the uncoordinated water mol-ecules and the ligand stablizes the structure of the complex.
