The title complex, [Co(C(4)H(5)O(6))(2)(H(2)O)(2)]·2H(2)O, contains a Co(II) ion, two single deprotonated tartrate anions, two coordinated water mol-ecules and two lattice water mol-ecules. The coordination geometry of the Co(II) ion is a distorted octa-hedron with two O atoms from two coordinated water mol-ecules occupying cis positions in the equatorial(More)
In the title compound, C(8)H(10)N(2)O(4)·H(2)O, the imidazole N atom is protonated and one of the carboxyl-ate groups is deprotoned, forming a zwitterion. An intra-molecular O-H⋯O hydrogen bond occurs. The crystal structure is stabilized by inter-molecular N-H⋯O and O-H⋯O hydrogen bonds. In addition, inter-molecular N-H⋯O and O-H⋯O hydrogen bonds link the(More)

In the title compound, C(11)H(11)NOS(2), the benzine ring is coplanar with the thia-zole ring, making a dihedral angle of 0.81 (1)°. In the crystal, adjacent mol-ecules are connected into a helical chain along the b axis by S⋯S contacts [3.4345 (18) Å]. These helical chains are further assembled into a three-dimensional supermolecular network by(More)

The reaction of aminophosphinic acid with CdCl2·2.5H2O or CoCl2·6H2O in concentrated hydrochloric acid yielded the isostructural compounds 1,4-bis{[hydroxy(phenyl)phosphoryl]methyl}piperazine-1,4-diium tetrachloridocadmate(II) dihydrate, (C18H26N2O4P2)[CdCl4]·2H2O, (I), and 1,4-bis{[hydroxy(phenyl)phosphoryl]methyl}piperazine-1,4-diium(More)
In the title compound, [Fe(C(5)H(3)N(2)O(4))(2)(H(2)O)(2)], the Fe(II) ion lies on an inversion centre and is coordinated by two N and two O atoms from two 5-carb-oxy-1H-imidazole-4-carboxyl-ate ligands and two water mol-ecules in a distorted octa-hedral geometry. An intra-molecular O-H⋯O hydrogen bond occurs. In the crystal, inter-molecular N-H⋯O and O-H⋯O(More)

In the title compound, C(15)H(11)NO(4), the dihedral angle formed by the benzene ring and the essentially planar 2-benzofuran ring system is 55.93 (3)°. In the crystal, inter-molecular O-H⋯O hydrogen bonds link pairs of mol-ecules, generating centrosymmetric R(2) (2)(8) ring motifs. These dimeric units are connected via N-H⋯O hydrogen bonds, forming C(6)(More)
