R.M and Y.S acknowledge UGC – India for a RFSMS fellowship (Sanction no. UGC/740/RFSMS) and DST – India (Sanction no. (SR/FT/CS-107/2011) for financial support. DST-FIST and DST-PURSE are acknowledged for providing the X-ray diffraction and ESI-MS facilities respectively at the Department of Chemistry, University of Calcutta. The magnetic measurements were financed by a subsidy for statutory activity from the Ministry of Science and Higher Education of the Republic of Poland for the Faculty of Chemistry, University of Wroclaw. The DFT computations were performed using computers of the Wrocław Centre for Networking and Supercomputing (Grant No. 47).

N2 - The present work introduces a family of MnIII4LnIII2(LnIII = SmIII, GdIII, DyIII) coordination clusters having a multisite hydroxyl rich ligand, 3-[(2-hydroxy-3-methoxy-benzylidene)-amino]-propane-1,2-diol (H3Vapd), namely [MnIII4SmIII2(Vapd)4(OAc)6]·4H2O (1), [MnIII4GdIII2(Vapd)4(OAc)6]·4H2O (2) and [MnIII4DyIII2(Vapd)4(OAc)6]·4H2O (3). The SmIIIanalog is the first example of a Mn4Ln2species reported to date. The similarities and differences in terms of structure, topology and magnetic behaviors within the series are investigated extensively. DFT computations were carried out for MnIII4GdIII2to address the experimentally challenging questions regarding the nature of the magnetic interactions in this cluster.
