The structure of a copper(I)-schiff base complex [CuN(CH2CH2NCHC6H5)3]+[BPh4]−

Abstract A crystal structure analysis of [CuN(CH 2 CH 2 NCHC 6 H 5 ) 3 ] + [BPh 4 ] − reveals that the complex has approximate three-fold symmetry in the solid state with the copper(I) atom having trigonal-pyramidal geometry. Principal dimensions are CuN (apical) 2.232(2), CuN(equatorial) 2.004, 2.006 and 2.019(2) A, N(ap)CuN(eq) 83.7–84.6(1)°. The CuH distances to the ortho -phenyl hydrogen atoms are too long to be considered agostic. The 1 H NMR spectrum is consistent with a similar structure for the copper(I) cation complex in solution.
