Description	Two enantiomeric Schiff base ligands R-/S-H2Lin situ generated from the condensation of o-vanillin with R- or S-2-phenylglycinol were applied to assemble chiral multinuclear transition metal magnetic clusters for the first time. Four new enantiomerically pure chiral clusters, [NaMn4(3-O)(N3)1.75Br0.25(R-L)3(MeOH)2(H2O)2][NaMn4(3-O)(N3)2(R-L)3(MeOH)2(H2O)2]Br4 ( 1R), [NaMn4(3-O)(N3)1.75Br0.25(S-L)3(MeOH)2(H2O)2][NaMn4(3-O)(N3)2(S-L)3(MeOH)2(H2O)2]Br4 ( 1S), [Cu6(R-L)2(R-HL)2(N3)5(MeOH)]NO3?2MeOH?H2O ( 2R) and [Cu6(S-L)2(S-HL)2(N3)5(MeOH)]NO3?2MeOH?H2O ( 2S), have been synthesized and characterized by single crystal X-ray crystallography and CD spectroscopy. Three Mn(III) in the MnIIMnIII3 clusters of 1R and 1S are joined together through the 3-O bridge to form an oxo-centered Mn3O unit. Three L2- link four manganese atoms via the 2-O,N,O-bridging manner into a MnIIMnIII3 cluster in a distorted tetrahedral geometry.
