Solid state coordination chemistry of microporous metal-organic frameworks of the cadmium(II)-4-pyridyltetrazolate family: the structural influences of chloride incorporation

While the metal-organic framework [Cd-4(OH)(2)(4-pt)(6)(DMF)(4)] center dot 12DMF (1 center dot 12DMF) (4-pt = 4-pyridyltetrazolate) is constructed from binuclear metal subunits, linked into porous {Cd-2(OH)(DMF)(2)(4-pt)(3)}(6) cages, introduction of increasing concentrations of chloride yields the 3-D framework materials, [Cd4Cl3(4-pt)(4)(OH)(DMF)(3)] center dot 8DMF center dot 14MeOH (2 center dot 8DMF center dot 14MeOH) and [Cd5Cl6(4-pt)(DMF)(2)(H2O)(2)] center dot 10DMF (3 center dot 10DMF), constructed from tetranuclear and chain building blocks, respectively.
