N2 - A series of isomorphous second-sphere coordination compounds [M II(DABP)3]3[Cr(C2O4) 3]2·14H2O (DABP≤5,5′-diamino-2, 2′-bipyridine; M≤Cu (1), Ni (2), Fe (3), Zn (4), and Mn (5)) have been constructed through multiple charge-assisted NH--O hydrogen-bonding interactions between the oxalate ligands in [Cr(C2O4) 3]3- (unit B) and the NH2 groups in the [M(DABP)3]2+ complex (unit A). The chiral [M(DABP) 3]2+ cations and [Cr(C2O4) 3]3- anions with the same (or ) configuration interdigitate alternately, affording linear A3B2 secondary building units. Two adjacent A3B2 units adopting opposite configurations are linked by a six-cornered star-shaped 14-water cluster of S 6 symmetry (unit C) to form a racemic 1D linear chain A 3B2(A)CA3B2(A)C. The microstructure of compound 1 shows a 3D flower-like morphology.
