Solvothermal syntheses and magnetic properties of two new coordination polymers with mixed ligands

Two new coordination polymers, [Ni(H2O)(BDC)(bpp)](n) (1) and [Co(mBDC)(bpp)](n) (2) (BDC = 1,4-benzene dicarboxylate anion; bpp = 4.4'-trimethylene dipyridine; mBDC = 1,3-benzene dicarboxylate anion), were synthesized by solvothermal reaction and structurally characterized. Single crystal X-ray diffraction showed that 1 consists of an inclined interpenetration of 1D nets generating an overall 3D entanglement and compound 2 of 1D chains. The luminescent and magnetic properties of both compounds in the solid state were also investigated, Crystal data: 1: orthorhombie, Pnna; a = 18.3648(6), b = 13.6854(4), c = 16.2307(5) angstrom, V = 4079.3(2) angstrom(3), and Z = 8. Crystal data: 2: triclinie, P (l) over bar; a = 8.6966(4), b = 10. 1093(4), c = 11.8334(4) angstrom, alpha = 68.263(1)degrees, beta = 82.895(1)degrees, gamma = 78.370(1)degrees, V = 945.16(7) angstrom(3), and Z = 2.
