%X One imine function of (3,5,7,7,13,15,15-heptamethyl-1,4,8,12-tetraazacyclopentadeca-4,12-diene)nickel(II) is reduced by NaBH4 to form the mono-imine-triamine cation, which forms an orange, S = 1, perchlorate salt and a blue-violet, S = 3, dithiocyanato compound. The structure of (1RS,3SR,8SR,12SR,13RS)-(3,5,7,7,13,15,15-heptamethyl-1,4,8,12-tetraazacyclopentadeca-4-ene-N1,N4,N8,N12) nickel(II) perchlorate is reported. The unit cell contains two independent but closely similar cations, with tetrahedrally-twisted square-planar coordination &#123;mean deviations from N4 planes; &#177; 0.23 &#197;, with Ni 0.05 &#197; from the plane; mean distances; Ni&#8211;Namine 1.925(5), Ni&#8211;Nimine 1.907(9) &#197; &#91;C18H38Cl2N4NiO8, triclinic, space group P1, a 8.6793(2), b 8.6808(2), c 16.8278(4) &#197;, &#945; 90.080(1), &#946; 90.004(1), &#947; 93.348(1)&#176;, Z 2, R 1 0.063 for 9906 reflections with I&#62;2&#963; (I)&#93;&#125;.
