The pyranoid rings are in a half-boat conformation in compound (I), C13H14ClO6P, and in a deformed half-boat-towards-half-chair conformation in compound (II), C11H12ClO4P. Fusion with the pyranoid ring has no significant influence on the planarity of the benzene ring in either compound. In both structures, the dimethoxyphosphoryl group is attached axially. The presence of the methoxycarbonyl substituent in (I) seems responsible for the disorder observed in the dimethoxyphosphoryl group.

The saturated part of the isoquinoline moiety in the title compound, C17H19NO2, has a twist conformation and the phenyl ring substituent is in an equatorial position. The absolute configuration of the molecule is R and molecules form infinite chains by means of weak hydrogen bonds.

The title molecule, C14H17ClO8P2, consists of two six-membered condensed rings, with a Cl atom at position 4 and a dimethoxyphosphoryl(dimethoxyphosphoryloxy)methylene group at position 2. Both rings are aromatic. The best planes of the two rings form a dihedral angle of 178.5(1)-degrees. The Cl atom lies 0.012(2) angstrom out of the plane defined by the ring. The molecule is the E isomer. The torsion angle O4-C3-C11-P19 is -174.2(2)-degrees.

The molecule contains an 18-membered heterocyclic ring which adopts a 'saddle-like' conformation with two non-linear diimino systems. A crystallographic two-fold axis passes through the centre of the ring. Two of the four benzene rings are nearly parallel to each other.
