Bis[3-chloro-6-(3,5-dimethyl-1H-pyrazol-1-yl)picolinato]nickel(II) tetra-hydrate.

ABSTRACT: In the title complex, [Ni(C(11)H(9)ClN(3)O(2))(2)]·4H(2)O, the Ni atom is coordinated by four N atoms and two O atoms derived from two tridentate 3-chloro-6-(3,5-dimethyl-1H-pyrazol-1-yl)picolinate ligands. The cis-N(4)O(2) donor set defines a distorted octa-hedral geometry. In the crystal structure, the complex and water mol-ecules are linked by O-H⋯O hydrogen bonds.

Bis[6-(3,5-dimethyl-1H-pyrazol-1-yl-κN)picolinato-κN,O]manganese(II) bis-(3,5-dinitro-benzoic acid) solvate.

Project description:In the title complex, [Mn(C(11)H(10)N(3)O(2))(2)]·2C(7)H(4)N(2)O(6), the Mn(II) atom has a disorted octa-hedral coordination formed by four N and two O atoms of two mer-6-(3,5-dimethyl-1H-pyrazol-1-yl)picolinate ligands (DMPP). Each of the two symmetry-independent 3,5-dinitro-benzoic acid mol-ecules is linked to the mol-ecule of the complex via a hydrogen bond involving its carboxylic H atom and one of the DMPP ligands of the complex. However, in one of the DMPP ligands, the non-coordinated carbonyl O atom serves as the hydrogen-bond acceptor, whereas in the second ligand it is the Mn-coordinated O atom which is involved in the hydrogen bonding.

Bis{4-[(3,5-dimethyl-1H-pyrazol-4-yl)selan-yl]-3,5-dimethyl-1H-pyrazol-2-ium} chloride monohydrate.

Project description:In the title compound, 2C(10)H(15)N(4)Se(+)·Cl(-)·OH(-), a singly protonated mol-ecule of the organic selenide participates in hydrogen bonding with neighboring mol-ecules, forming zigzag chains along [001].

Additionally, O-H⋯Cl hydrogen bonds are formed.

Poly[[bis-{?(3)-2-[(3,5-dimethyl-1H-pyrazol-1-yl)(phen-yl)meth-yl]propane-dioato}tetra-sodium(I)] 7.5-hydrate].

Project description:The asymmetric unit of the title polymer, {[Na(4)(C(15)H(14)N(2)O(4))(2)]·7.5H(2)O}(n), contains two 2-[(3,5-dimethyl-1H-pyrazol-1-yl)(phen-yl)meth-yl]propane-dioate (ppmp) anions, eight water mol-ecules (one located on a twofold rotation axis) and five sodium cations (one located on an inversion center and the other one located on a twofold rotation axis). The carboxyl-ate groups of the ppmp anions and the water mol-ecules bridge the Na cations, forming a two-dimensional polymeric structure. In the structure there are two types of coordination environment around the metal cations: one Na cation is coordinated by five O atoms in a distorted square-pyramidal geometry while the other four Na cations are coordinated by six O atoms in a distorted octa-hedral geometry. Extensive O-H?O and O-H?N hydrogen bonding is present in the crystal structure. The H atoms of one methyl group of the ppmp anion are disordered equally over two positions.

?-Oxido-bis{[2,2-bis-(3,5-dimethyl-1H-pyrazol-1-yl)acetato-?N,O,N]chloridooxidomolybdenum(V)} mono-hydrate.

Project description:In the binuclear title compound, [Mo(2)(C(12)H(15)N(4)O(2))(2)Cl(2)O(3)]·H(2)O, the complex mol-ecules have approximate C(2) symmetry. Both Mo(V) atoms have a distorted octa-hedral coordination environment with cis-positioned terminal chloride and oxide groups. The heteroscorpionate organic ligand binds to the Mo(V) atom via an N(2)O donor set. The water mol-ecule bridges two complex mol-ecules, forming O-H?O and O-H?Cl hydrogen bonds to the acetate group and to the chloride ligands.
