Trisiloxane-centred metal–organic frameworks and hydrogen bonded assemblies†
Abstract
A hexacarboxylic acid with a trisiloxane backbone (L-H6) has been prepared and applied in MOF construction. L-H6 itself crystallizes as an unusual 2D hydrogen-bonded network. Reaction of L-H6 with Mn(II) gave IMP-20 and with Zn(II) gave IMP-21: both are 3D MOFs incorporating Si–O–Si–O–Si linkages.
