N2 - The crystal structures of [(en)2NiCl2Ni(en)2] Cl2 (1) and [(en)2NiCl2Ni(en)2] (C1O4)2 (2) have been redetermined from single-crystal X-ray diffraction data at 295(1) K and refined by least squares to residuals of 0·073 and 0·052 respectively for 1345 and 1605 ‘observed’ reflections respectively. Crystals of (1) are monoclinic, P21n, a 14·053(4), b 11·309(3), c 6·326(1) Å, β 94·22(2)°, Z 2. Crystals of (2) are monoclinic, P21n, a 8·885(12), b 19·707(20), c 7·120(8) Å, β 108·99(4)°, Z 2. In both (1) and (2), a dimeric complex cation is observed, a pair of cis coordination sites about the nickel in each case being occupied by the bridging chlorines; the latter are asymmetric (Ni-Cl, 2·461(3), 2·551(3) (1); 2·461(3), 2·512(3) Å (2)).
