In the title compound, is-ammine(benzohydrazide-N')-dichloroplatinum(I
I), cis-[PtCl2(C7H8N2O)(NH3)], the benzoylhydrazine ligand is bonded t
o the Pt atom through its amino group. The Pt-Cl and Pt-N distances ar
e in the ranges 2.293 (5)-2.318 (5) and 2.01 (1)-2.08 (1) Angstrom, re
spectively. The arrangement of molecules in the monoclinic unit cell a
pproximates P2(1)/c space-group patterns; however, the true space-grou
p symmetry is P2(1). The two crystallographically independent molecule
s have significantly different conformations about the Pt-N(hydrazine)
bond. The structure is held together by a complicated network of N-H.
