Self-assembly of Cd(phen)(2+) and Cu(phen)(2+) (phen = 1,10-phenanthroline) building blocks with the bent ligand 4,4'-dithiodipyridine (dtdp) has been investigated. Both building blocks serve as corner units with constrained cis-geometry. The arched chain coordination polymer [{Cd(phen)(mu-dtdp)(dtdp)(H2O)}(ClO4)(2)center dot 2CH(3)OH center dot 1.5H(2)O](n) (1) crystallised from a mixture of Cd(ClO4)(2)center dot H2O, phen and dtdp in methanol. The reaction of [Cu(phen)(H2O)(2)](CF3SO3)(2) (2) with dtdp in an ethanol/water mixture yielded a chair-like metallamacrocycle, [{Cu(phen)(CF3SO3)(2)}(2)(mu-dtpd)(2)] (3). The crystal structure of the precursor complex 2 is also reported.
