Novel Zn(II) coordination polymer based on 1,2-bis (4-pyridyl)hydrazine - From two-dimensional to three-dimensional network

Two MOFs were reported based on Zn(H) with 1,2-bis(4-pyridyl)hydrazine (L1); a two-dimensional interpenetrating MOF I of formula [Zn-2(L1)(2)(L2)(2)](infinity) was formed with terephthalic acid (L2) as an additional linker. A three-dimensional MOF II of formula [Zn-2(L1)(2)(L3)(2)](infinity), was formed with the use of a larger spacer 2,6-naphthalenedicarboxylic acid (L3). MOF H consists of large porosity with a total volume of 3746 angstrom(3) that occupies 34.1% of the unit cell.
