3,4-Dimethyl-pyrano[2,3-c]pyrazol-6(2H)-one.


ABSTRACT: The asymmetric unit of the title compound, C(8)H(8)N(2)O(2), comprises two independent mol-ecules in both of which, all non-H atoms lie in a common plane (r.m.s. deviation = 0.014 and 0.017?Å). In the crystal, N-H?O hydrogen bonds connect the mol-ecules into zigzag chains running along [10-1]. Weak C-H?O inter-actions connect the chains into an infinite network.

The asymmetric unit of the title compound, C(8)H(8)N(2)O(2), comprises two independent mol-ecules in both of which, all non-H atoms lie in a common plane (r.m.s. deviation = 0.014 and 0.017 Å). In the crystal, N-H⋯O hydrogen bonds connect the mol-ecules into zigzag chains running along [10-1]. Weak C-H⋯O inter-actions connect the chains into an infinite network. ...[more]
