Synthesis, structure and topological analysis of a novel three dimensional Co(II) coordination polymer constructed by an unsymmetrical ligand

Abstract

Through in situ basic hydrolysis of cyanide functional group of 3-(1H-benzo[d]imidazol-1-yl)-5-(1H-imidazol-1-yl)benzonitrile a new three dimensional porous coordination polymer {[Co2(BIIBA)3]·(NO3)·5H2O}n (1) (BIIBA=3-(1H-benzo[d]imidazol-1-yl)-5-(1H-imidazol-1-yl)benzoate) have been isolated under hydrothermal conditions and characterized by single crystal X-ray diffraction. Topological analysis of 1 revealed a (3,3,4,5)-connected 4-nodal unprecedented pkb8 net with point symbol {4.62}2{42.66.82}{63}{65.8}.
