Abstract
An unprecedented pentanuclear hetero-bimetallic complex has been obtained by a self-assembling process between {Cu2L}2+ binuclear cationic units and [Mo(CN)8]4− anions. The compound with the formula [{CL}2(µ-NC)2MoIV(CN)6(CH3OH)1.5(H2O)0.5] · [{CL}2(µ-NC)2MoIV(CN)6(CH3OH)2] · 5H2O · 7.5CH3OH (1) (H2L = binucleating Schiff-base obtained by condensation of 2,6-diformyl-4-methylphenol with 1,3-propylenediamine), 1, crystallizes in P 1 triclinic space group and consists of two pentanuclear species, [{CL}2(µ-NC)2MoIV(CN)6(CH3OH)1.5(H2O)0.5] (A), [{CL}2(µ-NC)2MoIV(CN)6(CH3OH)2] (B) and solvent. In each unit, two {Cu2L}2+ cations are bridged by one octacyanidomolybdate, via two cis-cyanido groups. Non-covalent channel motifs are developed through a complex network of supramolecular interactions (hydrogen bonds, π–π stacking interaction) involving A and B units and lattice solvent molecules.
