Synthesis, structures and properties of two novel supramolecular polymers of Cu(I) with 1,1′-Bis(isoquinoline)-1,4-Phenyldimethylenyl

Two new complexes {(BIQPM)(2)[Cu4I8]center dot DMF}(n) (1) and {(BIQPM)[Cu-2(SCN)(4)]}(n) (2) [ BIQPM = 1,1'-Bis(isoquinoline)-1,4-Phenyldimethylenyl] have been synthesized via the self-assembly reaction in solution. Single-crystal X-ray diffraction analysis shows compound 1 is a tetranuclear oligomer and 2 is a 1D chain. Compound 1 crystallizes in the monoclinic system with space group C2/m; Compound 2 crystallizes in the triclinic system with space group P-1. It is the H-bonds and electrostatic interactions between the organic counteractions and inorganic moieties that do the contribution to the crystal packing. These compounds have been further characterized by IR spectroscopy and thermostability.
