Popis:	The scorpionate ligands containing 3-phenylpyrazole have been identified as possessing intermediate steric bulk, due to the wide range of structural types that have been characterized in complexes of these ligands. In this paper, we report the syntheses and structures of a number of complexes containing hydrotris(3-phenylpyrazol-1-yl)borate and dihydrobis(3-phenylpyrazolyl)borate which further manifest the versatility of these ligands. The syntheses and solid-state structures of TpPhFe(SCN)(THF) (I), TpPhFe(NO3)2 (II), TpPhCuCl(pzPh) (III), TpPhCu(SCN)(pzPh) (IV), BpPh 2Co (V), and TpPhBpPhCo (VI) are reported (TpPh=hydrotris(3-phenylpyrazolylborate); BpPh=dihydrobis(3-phenylpyrazolylborate); pzPh=3-phenylpyrazole). Compound I displays a trigonal bipyramidal coordination sphere, while III and IV are square-pyramidal. Compound II contains one monodentate and one bidentate nitrate ligand in a distorted octahedral coordination sphere. Compound V is tetrahedral and VI is octahedral with an agostic CoH interaction in the sixth coordination site.
