Crystal data for1: [Co3(NC5H3(CO2)2-2,5)2(μ3-OH)2(OH2)2], C14H12Co3N2O12,M= 577.05, monoclinic, space groupP21/n,a= 6.6426(2) Å,b= 11.3188(4) Å,c= 22.6559(10) Å, β = 92.6329(15)°,V= 1701.63(11) Å3,Z= 4,T= 180(2) K. Refinement of 292 paramaters on 2859 independent reflections out of 9111 total measured reflections (Rint= 0.0644) led toR1= 0.072, wR2= 0.158, andS= 1.077.
