Solvent-free synthesis of inorganic-organic hybrid solids with chainlike, layered, and open-framework structures

Abstract

Three inorganic-organic hybrid solids, namely, Cd2(phen)2(H2PO4)(H2PO3)(C2O4) (1), (H2dab)0.5·Co(H2PO3)(C2O4) (2), and Hdbu·In2(HPO3)2(C2O4)1.5 (3), were prepared under solvent-free conditions, where phen = 1,10-phenanthroline, dab = 1,4-diaminobutane, and dbu = 1,8-diazabicyclo[5.4.0]undec-7-ene. These compounds have chainlike, layered, and three-dimensional structures, respectively. Compound 1 shows a weak second harmonic generation response. The temperature dependence of the magnetic susceptibility of compound 2 was also investigated.
