[Ni-7(OH)(6)(L-1)(6)](NO3)(2)center dot 2MeOH (2),

[Zn-7(OH)(6)(L-1)(6)](NO3)(2)center dot 3MeNO(2) (6) (where HL1 =
2-iminomethyl-6-methoxy- phenol, HL2 =
2-iminomethyl-4-bromo-6-methoxy-phenol). Each member exhibits a
double-bowl pseudo metallocalix[6]arene topology whereby the
individual [M-7] units form molecular host cavities which are able to
accommodate various guest molecules (MeCN, MeNO2 and MeOH). Magnetic
susceptibility measurements carried out on complexes 1 and 4 indicate
weak exchange"
