A donor-acceptor compound composed of a dinuclear zinc(II) complex of a Robson macrocycle with 8-methylquinoline

A donor-acceptor compound, diaqua-1 kappaO,2 kappaO-[mu -11,23-dimethyl-3,7 ,15,19-tetraazatricyclo[19.3.1.1 9,13]hexacosa-1(25),2,7,9,11,13(26),14,19, 21,23-decaene-25,26-diolato-1 kappa N-4(3),N-7,- O-25,O-26:2 kappa N-4(15), N-19,O-25,O-26]dizinc(II) diperchlorate bis(8-methylquinoline) ethanol diso lvate, [Zn-2(C24H26N4O2)(H2O)(2)](ClO4)(2). 2C(10)H(9)N . 2C(2)H(6)O, obtai ned by the reaction of a dinuclear zinc(II) complex of a Robson macrocycle (acceptor) and 8-methylquinoline (donor), lies about an inversion centre an d the coordination about the unique Zn atom is a distorted square pyramid. The fifth coordination site is occupied by the water molecule, Zn-O = 2.016 (2) Angstrom, and the average macrocyclic Zn-O and Zn-N distances are 2.05 9 (6) and 2.059 (3) Angstrom, respectively.
