We report the synthesis and magnetic characterisation of a series of planar [M(7)] (M= Ni(II), Zn(II)) disc complexes [Ni(7)(OH)(6)(L(1))(6)](NO(3))(2) (1), [Ni(7)(OH)(6)(L(1))(6)](NO(3))(2)center dot 2MeOH (2), [Ni(7)(OH)(6)(L(1))(6)](NO(3))(2)center dot 3MeNO(2) (3), [Ni(7)(OH)(6)(L(2))(6)](NO(3))(2)center dot 2MeCN (4), [Zn(7)(OH)(6)(L(1))(6)](NO(3))(2)center dot 2MeOH center dot H(2)O (5) and [Zn(7)(OH)(6)(L(1))(6)](NO(3))(2)center dot 3MeNO(2) (6) (where HL(1) = 2-iminomethyl-6-methoxy- phenol, HL(2) = 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, MeNO(2) and MeOH). Magnetic susceptibility measurements carried out on complexes 1 and 4 indicate weak exchange
