Bis(phenyl-phospho-nic) anhydride.

ABSTRACT: The asymmetric unit of the title compound, C(12)H(12)O(5)P(2), contains four independent mol-ecules, generating two dimers via pairs of inter-molecular O-H?O hydrogen bonds, forming R(2) (2)(8) rings. The two aryl rings of each mol-ecule form dihedral angles of 108.6?(1), 103.2?(1), 12.5?(2) and 8.1?(2)° in the four mol-ecules.

The asymmetric unit of the title compound, C(12)H(12)O(5)P(2), contains four independent mol-ecules, generating two dimers via pairs of inter-molecular O-H⋯O hydrogen bonds, forming R(2) (2)(8) rings. The two aryl rings of each mol-ecule form dihedral angles of 108.6 (1), 103.2 (1), 12.5 (2) and 8.1 (2)° in the four mol-ecules. ...[more]
