Four novel compounds, [NH3CH2CH2OH][MIIIMII(HCOO)6] with MIII = Fe and MII = Mn (HEAFeMn), MIII = Fe and MII = Ni (HEAFeNi), MIII = Cr and MII = Mn (HEACrMn) and MIII = Cr and MII = Co (HEACrCo), have been synthesized. They crystallize in the trigonal niccolite-type structure (space group P 3¯ 1c). Magnetic studies revealed that HEAFeNi, HEAFeMn and HEACrCo are weak ferromagnets with the ordering temperature of 43, 27 and 11K, respectively, whereas HEACrMn does not order magnetically at least down to 2K. A source of the ferromagnetic component is most likely a canting of the antiferromagnetically ordered moments by a small angle resulting from antisymmetric exchange or single-ion anisotropy. Raman and IR data confirm that all obtained samples are isostructural. Optical studies of HEACrMn show that local crystal field around Cr3+ ion is of intermediate strength with the Dq/B value of 2.57. Luminescence studies indicate that HEACrMn exhibits efficient Cr3+-based emission. Below 200K, the 2E-4A2 phosphorescence observed as two bands at 686 and 696nm becomes predominate.
