A new type of crystal packing with µ6-bridged squarate anions has been found in the structure of Mn2(OH)2(C4O4) 1 during magnetic and X-ray single crystal diffraction measurements performed over a wide range of temperatures; the unit cell parameters for the crystal remain remarkably unchanged in the interval from 10 to 120 K.
