The investigation reveals the formation of two different compounds of one\u2010 or three\u2010dimensions starting from the same reaction mixture that differs only in pH. Isolated compounds have been characterized by IR and elemental analysis; both compounds were also successfully characterized by single\u2010crystal X\u2010ray diffraction. This study shows that the gradual increase in pH helps to construct a higher\u2010dimensional network. Catalytic activity of compounds <jats:bold>1<\/jats:bold> and <jats:bold>2<\/jats:bold> was tested for the Claisen\u2013Schmidt reaction. Compound <jats:bold>2<\/jats:bold> was successfully dehydrated to produce a coordinately unsaturated compound <jats:bold>2\u2009a<\/jats:bold>, which shows higher catalytic activity than
