Abstract	Employment of 2-OH-naph (2-hydroxy-1-naphthaldehyde) and aibH (2-amino-isobutyric acid) in CrIII-MII (MII: Mn, Fe, Co, Ni) chemistry led to the isolation of a family of 1D coordination polymers. Four new mixed metal chromium 1D coordination polymers were isolated and characterized: [Cr2IIIMnII (L)4(MeOH) 2]n (1), [Cr2IIIFeII (L)4(MeOH) 2]n (2), [Cr2IIICoII (L)4(MeOH) 2]n (3), [Cr2IIINiII (L)4(MeOH) 2]n (4), (L: (Z)-2-(((2-hydroxynaphtalen-1-yl) methilene)amino)-2-methilpropionate). The complexes were characterized by Single-Crystal X-ray Crystallography, Elemental Analysis, EDS Spectroscopy, DC and AC magnetic susceptibility measurements, IR spectroscopy and PXRD measurements. The magnetic studies of complex 4 showed that the cluster is i) the first CrIII/NiII Single Chain Magnet ever reported, with Ueff =143.4 K and τ0 =0.4• 10-13 s and ii) the second only example of a Single Chain Magnet containing trivalent chromium centers.
