Contents:
Two divalent metal phosphonates with a layered structure, Zn(H2L) (1) and Cd2L (2) (H4L = CH3CH2CH2N(CH2PO3H2)2), have been hydrothermally synthesized and characterized by single-crystal X-ray diffraction as well as with infrared spectroscopy, elemental analysis and thermogravimetric analysis. The structure of 1 shows a layered structure in which the 1D zinc(II) phosphonate chains are interconnected by bridging organic groups to form 2D layers. In 2, the interconnection of [CdO5N] and [CdO5] polyhedra via edge-sharing forms a dimer. The dimers are interconected by [CPO3] tetrahedra via corner-sharing to form 2D double layers in the bc-plane.
