YBa2 ( Cu ~ \_ xMx ) 4Os ( M = Fe, Co, Ni, Zn and Ga; 0 ~< x ~< 0.05 ) h ave been investigated by means of X-ray diffraction, electrical-resistivity and magnetic-susceptibility measurements. X-ray-diffraction patterns show that all samples studied contain the nearly single 124 phase. They exhibit an

## Abstract We report the synthesis, crystal structures, and spectral, thermal, and magnetic properties of a family of metal–organic perovskite ABX~3~, [C(NH~2~)~3~][M^II^(HCOO)~3~], in which A=C(NH~2~)~3~ is guanidinium, B=M is a divalent metal ion (Mn, Fe, Co, Ni, Cu, or Zn), and X is the formate
