Graphical abstract A new cyanide-bridged 1D FeIIICoII complex has been designed and synthesized. The complex is overall ferromagnetic and exhibits typical metamagnet behaviors with T N = 2.6 K and H c = 1.2 kOe at 2.0 K. Highlights • A new cyanide-bridged 1D FeIIICoII complex has been synthesized. • The complex is overall ferromagnetic, which is fitted by 1D magnetic model. • The complex exhibits typical metamagnet behaviors with T N = 2.6 K. Abstract A new cyanide-bridged FeIIICoII bimetallic complex {[Fe(Tp)(CN) 3 Co(L N3O2)]ClO 4 ·2H 2 O} n (Tp− = hydrotris(pyrazolyl)borate, L N3O2 = 2,13-dimethyl-6,9-dioxa-3,12,18-triaza-bicyclo[12.3.1]octadeca-1(18),2,12,14,16-pentene) (1) has been synthesized based on the building blocks of [CoII(L N3O2)(H 2 O) 2 ](ClO 4) 2 and Bu 4 N[FeIII(Tp)(CN) 3 ]. X-ray single crystal diffraction analysis shows that complex 1 has a cyanide-bridged Fe(III) and Co(II) alternating one-dimensional (1D) zigzag-like structure. Magnetic investigations on complex 1 indicate the ferromagnetic coupling between Fe(III) and Co(II) through cyanide bridge. Complex 1 displays long-range antiferromagnetic ordering with T N = 2.6 K. The typical metamagnet behaviors have been observed with the critical field of ca. 1.2 kOe at 2.0 K. [ABSTRACT FROM AUTHOR]
