In this first paper we revisit the complex dynamical state of A 85 by using independent methods. First, we analyze the galaxy redshift distribution towards A 85 in the whole range 0-40000km/s, and determine the mean redshifts of the background clusters A 87 and A 89, very close in projection to A 85. Then we search for substructures in A 85 by considering the 2D galaxy distribution of its members (13000-20000km/s) and by applying the kinematical 3D Δ-test to both projected positions and radial velocities. Description: We obtained position and optical magnitude data for galaxies in the A 85/87/89 complex from the SuperCOSMOS Science Archive, available from the Royal Observatory of Edinburgh, . The area covers a region of 50 arcmin radius around the center of A 85, taken as the position of its cD galaxy, MCG-02-02-086, which also coincides with the peak of the X-ray emission of the cluster. Magnitudes in bJ and rF bands came from the digitization of UKST Survey plates (IIIa-J + GG395 and IIIa-F + OG590, respectively) by the SuperCOSMOS machine, using 10um size pixels (0.67").
