Studies on solid solutions based on layered honeycomb-ordered phases P2-Na2M2TeO6 (M=Co, Ni, Zn)

► Solid solutions between lamellar phases Na2M2TeO6 (M=Co, Ni, Zn) are investigated. ► A M2+/X6+ honeycomb ordering characterized all the compositions. ► A structural transition is shown when Ni is replaced by Co or Zn. ► The low-temperature AFM ordering of Na2Ni2TeO6 and Na2Co2TeO6 is suppressed by zinc substitution. ► Color changes from pink to light green and white when M=Co, Ni, Zn, respectively.
