Aqua-bis(2-methyl-4-oxopyrido[1,2-a]pyrimidin-9-olato)zinc(II) monohydrate.

ABSTRACT: The crystal structure of the title compound, [Zn(C(9)H(7)N(2)O(2))(2)(H(2)O)]·H(2)O, involves discrete mononuclear complex mol-ecules. The special positions on the rotation twofold axis are occupied by Zn(II) and O atoms of the coordinated and uncoordinated water mol-ecules. The coordination around the Zn(II) atom can be described as transitional from trigonal-bipyramidal to square-pyramidal. The two chelating 2-methyl-4-oxopyrido[1,2-a]pyrimidin-9-olate ligands and the coordin-ated water mol-ecule form the Zn coordination. O-H⋯O hydrogen bonds between the coordinated water mol-ecule and the ligand and between the uncoordinated water mol-ecule and the ligand dominate the crystal packing.

Aqua-{6,6'-dieth-oxy-2,2'-[ethane-1,2-diyl-bis(nitrilo-methanylyl-idene)]diphen-olato}zinc.

Project description:The mononuclear zinc title complex, [Zn(C(20)H(22)N(2)O(4))(H(2)O)], was obtained by the reaction of 3-eth-oxy-salicyl-aldehyde, ethane-1,2-diamine, and zinc acetate in methanol. The Zn atom is five-coordinated by two phenolate O and two imine N atoms of the tetradentate Schiff base ligand and by one water O atom, forming a square-pyramidal geometry. In the crystal, pairs of mol-ecules are linked via inter-molecular O-H⋯O hydrogen bonds, forming dimers.

Aqua-bis(3'-hydr-oxy-2,2'-bipyridine-3-olato-?N,N')zinc(II).

Project description:In the title complex, [Zn(C(10)H(7)N(2)O(2))(2)(H(2)O)], the Zn(II) ion and water O atom are located on a crystallographic twofold rotation axis and the metal atom assumes a distorted trigonal-bipyramidal ZnN(4)O coordination geometry. An intra-molecular O-H?O hydrogen bond occurs within the ligand and inter-molecular O-H?O hydrogen bonds involving the water mol-ecule result in a sheet structure in the crystal structure. In addition, a short C-O?? contact between the O atom of the deprotonated hydroxyl group and a nearby pyridine ring [O?Cg = 3.977?(2)?Å, where Cg is the centroid of the pyridine ring] is observed.

Bis(isonicotinamide-κN)bis-[4-(methyl-amino)benzoato]zinc(II) monohydrate.

Project description:In the title Zn(II) complex, [Zn(C(8)H(8)NO(2))(2)(C(6)H(6)N(2)O)(2)]·H(2)O, the Zn atom is coordinated by two 4-methyl-amino-benzoate (MAB) and two isonicotinamide (INA) ligands in a distorted trigonal-bipyramidal geometry; one of the MAB ions acts as a bidentate ligand while the other MAB and the two INA are monodentate ligands. The dihedral angles between the carboxyl groups and the adjacent benzene rings are 8.52 (22) and 5.10 (14)°. In the crystal, inter-molecular O-H⋯O and N-H⋯O hydrogen bonding links the mol-ecules into a supra-molecular structure. Weak inter-molecular C-H⋯O inter-actions are also present.

Aqua-bis(isonicotinamide-κN)bis-(4-methyl-benzoato)-κO;κO,O'-cadmium(II) monohydrate.

Project description:In the crystal structure of the title compound, [Cd(C(8)H(7)O(2))(2)(C(6)H(6)N(2)O)(2)(H(2)O)]·H(2)O, the Cd(II) cation is coordinated by two 4-methyl-benzoate (PMB) anions, two isonicotinamide (INA) ligands and one water mol-ecule in a distorted octa-hedral CdN(2)O(4) geometry. One of PMB ions acts as a bidentate ligand while the other and the two INA are monodentate ligands. An O-H⋯O hydrogen bond links the uncoordinated water mol-ecule to the carboxyl groups of the complex. The dihedral angles between the carboxyl groups and the adjacent benzene rings are 10.28 (11) and 21.24 (9)°, while the two benzene rings and the two pyridine rings are oriented at dihedral angles of 6.90 (4) and 88.64 (4)°, respectively. In the crystal structure, O-H⋯O and N-H⋯O hydrogen bonds link the mol-ecules into a supra-molecular structure. A π-π contact between the benzene rings [centroid-centroid distance = 3.911 (1) Å] may further stabilize the crystal structure. Weak C-H⋯π inter-actions involving the pyridine rings also occur in the crystal structure.

Bis(2-amino-4-methyl-pyrimidin-1-ium) hexa-aqua-cobalt(II) disulfate dihydrate.

Project description:In the title hydrated mixed-cation salt, (C(5)H(8)N(3))(2)[Co(H(2)O)(6)](SO(4))(2)·2H(2)O, the complete octa-hedral hexa-aqua complex cation is generated by crystallographic inversion symmetry. In the crystal, the components are linked by O-H⋯O and N-H⋯O hydrogen bonds, the latter, involving pyrimidinium cations and sulfate anions, generating R(2) (2)(8) loops. These, together with π-π inter-actions between centrosymmetrically related pyrimidinium cations [centroid-centroid separation = 3.5460 (8) Å], lead to the formation of a three-dimensional network.
