Structure comparison of the complexes [Cu(bmdhp)](ClO(4)) (1) and [Cu(bmdhp)](SO(3)CF(3)) (2) with the previously reported [Cu(I)(bdhp)(H(2)O)](PF(6))(0.66)(BF(4))(0.34) (4), bdhp = 1,7-bis(1H-benzimidazol-2-yl)-2,6-dithiaheptane, with the related [Cu(I)(mmb)(2)](BF(4)) (5), mmb = 1-methyl-2-methylthiomethyl-1H-benzimidazole, with the oxidised [Cu(II)(bmdhp)(H(2)O)](ClO(4))(2) (7), and with the zinc(II) species [Zn(bmbdh)(H(2)O)(SO(3)CF(3))](SO(3)CF(3)) (8) and {[Zn(mu-bmdhp)(H(2)O)(SO(3)CF(3))](2)}(SO(3)CF(3)) (9) reveal a variety of coordination numbers, L(4) ligand coordination modes, M-N bond lengths and especially N-M-N angles...
