Abstract:
In the title compound, [Mo(C(15)H(22)BN(6))(C(7)H(4)NO)(2)(NO)]·C(7)H(5)NO·CH(2)Cl(2), the central Mo(II) atom adopts a distorted cis-MoO(2)N(4) octa-hedral geometry with the hydro-tris-(3,5-dimethyl-pyrazolylborate) anion attached to the metal in an N,N',N''-tridentate tripodal coordination mode. Two O-bonded 4-cyano-phenolate anions and a nitrosyl cation complete the coodination of the Mo(II) atom. Two intra-molecular C-H⋯O and one C-H⋯N hydrogen bonds help to establish the configuration of the complex mol-ecule. The crystal structure is stabilized by inter-molecular C-H⋯N and C-H⋯O hydrogen bonds.

Structural Isomerism
Isomers are different chemical species that have the same chemical formula. Structural isomerism of coordination compounds can be divided into two subcategories, the linkage isomers and coordination-sphere isomers.
Linkage isomers occur when the coordination compound contains a ligand that can bind to the transition metal center through two different atoms. For example, the CN− ligand can bind through the carbon atom or through the nitrogen atom. Similarly, SCN− can be...
Nomenclature of Aromatic Compounds with Multiple Substituents
For disubstituted benzene derivatives, with two groups attached to the benzene ring, three constitutional isomers are possible. For example, consider dimethyl benzene, often called xylene, where the second methyl group can be substituted at the second, third, or fourth carbon. The relative position of the substituents is represented by prefixes ortho, meta, or...
