Three novel polyoxometalate derivatives decorated by transition metal complexes have been hydrothermally synthesized. Compound 1 consists of [(PMo6Mo2V8O44)-Mo-VI-V-V-O-IV{CO (2,2'-bipy)(2)(H2O)}(4)](3+) polyoxocations and [(PMo4Mo4V8O44)-Mo-IV-V-V-O-IV{Co(2,2'-bipy)(2)(H2O)}(2)](3-) polyoxoanions, which are both built on mixed-metal tetracapped [PMo8V8O44] subunits covalently bonded to four or two {Co(2,2'-bpy)(2)(H2O)}(2+), clusters via terminal oxo groups of the capping V atoms. Compound 2 is built on [(PMo8V6O42)-V-VI-O-IV{Cu-I(phen)}(2)](5-) clusters constructed from mixed-metal bicapped [(PMo8V6O42)-V-VI-O-IV](7-) subunits covalently bonded to two {Cu(phen)}(+) fragments in the similar way to 1. The structure of 3 is composed of [(PMo9Mo3O40)-Mo-VI-O-V](6-) units capped by two divalent Ni atoms via four bridging oxo groups. The crystal data for these are the following: C120H126Co6Mo16N24O103P2V16 (1), triclinic P (1) over bar, a = 15.6727(2) Angstrom, b = 17.3155(3) Angstrom, c = 19.5445(2) Angstrom, alpha = 86.1520(1)degrees, beta = 81.2010(1)degrees, gamma = 63.5970(1)degrees, Z = 1; C120H85Cu6Mo8N20O44PV6 (2), triclinic P (1) over bar, a = 14.565(4) Angstrom, b = 15.899(3) Angstrom, c = 16.246(4) Angstrom, alpha = 116.289(2)degrees, beta = 103.084(2)degrees, gamma = 94.796(2)degrees, Z = 1; C60H40Mo12N10Ni3O40P (3), monoclinic P2(1)/c, a = 14.804(3) Angstrom, b = 22.137(4) Angstrom, c = 25.162(5) Angstrom, alpha = 90degrees, beta = 98.59(3)degrees, gamma = 90degrees, Z = 4.
