Magnetic interactions in a new geometrically frustrated system (Co1-xFex)2(OH)3Cl are investigated using magnetic susceptibility and μSR study. While Co2(OH)3Cl is ferromagnetic and Fe2(OH)3Cl antiferromagnetic, the partially substituted series (Co1-xFex)2(OH)3Cl show spin-glass behaviours, wherein ferromagnetic interactions prevail for low Fe concentration and antiferromagnetic ones prevail for high Fe concentration. In special, analysis of the AC magnetic susceptibility and ZF-μ+SR for the x=0.5 sample suggest that CoFe(OH)3Cl has both features of chemically disordered random spin glass and geometrically frustrated spin glass. It is also the first spin-glass system for the newly found geometric frustration series M2(OH)3X.
