Reactions between solutions of [Me 4 N] 4 [Nb 6 Cl 12 (CN) 6 ]‚2MeOH and [Mn(L)]Cl (L ) acacen 2-) bis(acetylacetonato)ethylenediamine at room temperature led to the formation of four compounds containing supramolecular assemblies formed of [Nb 6 Cl 12 (CN) 6 ] 4and [Mn(L)] + as building units. The four compounds were characterized by single-crystal X-ray diffraction, IR, elemental analysis, thermogravimetric analysis, and magnetic susceptibility measurements (for 3). In 1, each cluster is coordinated by one [Mn(L)(MeOH)] + via a CNligand to give an anionic dimeric unit {[Mn(L)(MeOH)][Nb 6 Cl 12 (CN) 6 ]} 3-, which connect to each other via hydrogen bonding between the CNligand and MeOH from the cations [Mn(L)(MeOH) 2 ] + to give anionic tubularlike chains. The structure of 2 comprises trimeric units {[Mn(L)(H 2 O)] 2 [Nb 6 Cl 12 (CN) 6 ]} 2in which each cluster is trans-coordinated by two [Mn(L)(H 2 O)] + cations via the CNligand. The trimeric units are connected to each other via hydrogen bonding between CNand the water of coordination to give anionic chains along the crystallographic a axis. The chains are connected to each other through further hydrogen bonding to give an overall three-dimensional hydrogen-bonded framework. In 3, each cluster is coordinated by two [Mn(L)(MeCN)] + and two [Mn(L)(H 2 O)] + via CNligand to give neutral pentameric units that are connected through hydrogen bonding between CNand aqua ligands to give hydrogen-bonded chains along the crystallographic b axis. 4 is based on two supramolecular ions; the cation consists of a heptameric unit {[Mn(L)(H 2 O)] 4 [Mn(L)] 2 [Nb 6 Cl 12 (CN) 6 ]} 2+ in which each cluster is coordinated by six [Mn(L)] + via CNligand, whereas the anion {[Mn(L)] 2 [Nb 6 Cl 12 (CN) 6 ]} 2is the same as that found in 2. Electrostatic interactions and hydrogen bonding between these two supramolecular species afford a 1D framework. Magnetic susceptibility shows that 3 is paramagnetic with four high-spin Mn(III) ions. Thermal behaviors of 1-4 are presented.
