In the cation of the title compound, [Mn(C(11)H(13)N(5))(2)](ClO(4))(2)·CH(3)CN, the metal atom is located on a twofold rotation axis and is six-coordinated by six N atoms from two different 2,6-bis-(4,5-dihydro-1H-imidazol-2-yl)pyridine (bip) ligands in a distorted octahedral geometry. The O atoms of the perchlorate anions are disordered with occupancies(More)
The asymmetric unit of the title compound, C(12)H(14)N(4)·C(8)H(6)O(4)·4H(2)O, consists of one half of the 1,4-bis-(4,5-dihydro-1H-imidazol-2-yl)benzene (bib) mol-ecule, one half of the terephthalic acid (TA) mol-ecule and two water mol-ecules. Both the bib and the TA mol-ecules reside on crystallographic inversion centers, which coincide with the centroids(More)
The asymmetric unit of the title compound, C(12)H(14)N(4)·2C(6)H(7)NO(3)S·2H(2)O, contains one half of a centrosymmetric 1,4-bis-(4,5-dihydro-1H-imidazol-2-yl)benzene (bib) molecule, one 4-amino-benzene-sulfonic acid molecule and one water mol-ecule. In the bib molecule, the imidazole ring adopts an envelope conformation. The benzene rings of bib and(More)
