Dichloridobis(3,5-dimethyl-1H-pyrazol-4-amine-κN)cobalt(II).

ABSTRACT: In the title compound, [CoCl(2)(C(5)H(9)N(3))(2)], the Co(II) atom adopts a slightly distorted tetra-hedral coordination geometry provided by two chloride anions and two N atoms from the organic ligands. The dihedral angle between the pyrazole rings is 85.91 (10)°. In the crystal structure, mol-ecules are linked into a three-dimensional network by inter-molecular N-H⋯N and N-H⋯Cl hydrogen-bonding inter-actions.

Project description:In the mononuclear title complex, [CoBr(2)(C(5)H(8)N(2))(2)], the Co(II) atom is coordinated by two N atoms from two monodentate 3,5-dimethyl-pyrazole ligands and two Br atoms in a highly distorted tetra-hedral geometry. In the crystal, the complex mol-ecules are linked by inter-molecular N-H⋯Br hydrogen bonds into chains along [101]. An intra-molecular N-H⋯Br hydrogen bond is also present.

Dichloridobis(3,4,5-trimethyl-1H-pyrazole-κN)cobalt(II).

Project description:In the title compound, [Co(II)Cl(2)(C(6)H(10)N(2))(2)], a pair of 3,4,5-trimethyl-pyrazoles act as monodentate ligands. Two Cl(-) anions are also bonded directly to the Co(II) atom, which has a CoN(2)Cl(2) chromophore in a slightly distorted tetra-hedral geometry. The two mol-ecules in the asymmetric unit are related by an approximate twofold rotation roughly parallel to the a axis. The amino H atom in the pyrazole ring participates in weak N-H⋯Cl hydrogen bonds to form chains that propagate roughly parallel to the c axis.
