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

Abstract

While the metal–organic framework [Cd₄(OH)₂(4-pt)₆(DMF)₄]·12DMF (1·12DMF) (4-pt = 4-pyridyltetrazolate) is constructed from binuclear metal subunits, linked into porous {Cd₂(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]·8DMF·14MeOH (2·8DMF·14MeOH) and [Cd₅Cl₆(4-pt)(DMF)₂(H₂O)₂]·10DMF (3·10DMF), constructed from tetranuclear and chain building blocks, respectively.
