In the title compound, [Ca(NO(3))(C(34)H(32)N(10))]NO(3)center dot 3CH(4)O, the Ca(II) ion is coordinated by six N atoms of the EDTB ligand {EDTB is N,N,N',N'-tetrakis[(2-benzimidazolyl)methyl]-1,2-ethanediamine} and two O atoms from the nitrate ligand, to form a distorted dodecahedral geometry. The crystal packing is stabilized by intermolecular N-H center dot center dot center dot O, N-H center dot center dot center dot N and O-H center dot center dot center dot O hydrogen bonds, which link the constituent units into a three-dimensional network. The uncoordinated nitrate anion is disordered over two sites, with fixed occupancies of 0.77 and 0.23.
