(Benzoato-κO,O')(5,5,7,12,12,14-hexa-methyl-1,4,8,11-tetra-azacyclo-tetra-decane-κN,N',N'',N''')nickel(II) perchlorate monohydrate.

ABSTRACT: The Ni atom in the title salt, [Ni(C(7)H(5)O(2))(C(16)H(36)N(4))]ClO(4)·H(2)O, is in a six-coordinate octa-hedral geometry. The metal atom is chelated by the carboxyl-ate group, and the macrocyclic ligand adopts a folded configuration. The cation, anion and water mol-ecules engage in hydrogen bonding to form a layer structure.

Project description:The title compound, [Ni(C(8)H(5)O(4))(C(16)H(36)N(4))]ClO(4)·H(2)O, has the Ni(II) atom in a distorted octa-hedral geometry, surrounded by coordination by four N atoms of the 5,5,7,12,12,14-hexa-methyl-1,4,8,11-tetra-azacyclo-tetra-decane ligand in a folded configuration, and two carboxyl-ate O atoms of the 2-carboxy-benzoate ligand in cis positions.

Project description:In the crystal structure of the title dinuclear compound, [Ni(2)(C(4)H(4)O(5))(C(16)H(36)N(4))(2)](ClO(4))(2)·H(2)O, the bridg-ing di-car-box-yl-ate dianion O,O'-chelates to two Ni atoms, both of which are also chelated by the N-macrocylic ligand. The Ni atoms exhibit a distorted octa-hedral coordination. N-H?O and O-H?O hydrogen bonds link the cations and the uncoordinated water mol-ecules into a layer structure; the perchlorate anions occupy the space between adjacent layers, and are only weakly linked to the layers. One of the perchlorate anions is disordered over two sets of sites in a 3:2 ratio.

3,3'-(5,5,7,12,12,14-Hexa-methyl-1,4,8,11-tetra-azacyclo-tetra-decane-1,8-diyl)di-propanonitrile methanol disolvate.

Project description:The asymmetric unit of the title compound, C(22)H(42)N(6)·2CH(4)O, comprises one half of a 14-membered tetra-azacyclo-tetra-decane macrocycle with cyano-ethyl substituents on one of the N atoms and a methanol solvent mol-ecule. The macrocycle lies about an inversion centre. The cyano-ethyl substituents are oriented so that the cyano groups lie over opposite faces of the central cavity of the macrocycle. The methanol solvate mol-ecules lie away from the cavity of the macrocycle and are linked to the macrocycles via O-H?N hydrogen bonds.
