| Abstract: | Self‐assembly of Cd(NO3)2 with o ‐phthalic acid monopotassium salt (KHphth) in the presence of ethylenediamine (en) produced a new heterometallic coordination polymer CdK2(phth)2(en)0.5(H2O)]n ( 1 ). Single‐crystal X‐ray analyses reveal that it crystallizes in a monoclinic space group P 21/c. a = 11.6707(6) Å, b = 8.1019(4) Å, c = 20.9503(11) Å, β = 94.6640(10)o. The complex displays an en‐pillared 3D framework, which is constructed from 2D CdK2(phth)2(H2O)]n layers featuring uncommon inorganic cadmium‐potassium‐oxide layers containing potassium‐oxide layers. In the solid state, complex 1 shows photoluminescence with the maximum emission intensities at 355 nm upon excitation at 312 nm. (© 2009 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim) |
